It looks like this height property was redundant prior to upgrading to angular/material 19.1.0-rc.0. An interaction between this property and that update caused elements inside of material expansion panels to be hidden.
This PR removes this unnecessary height assignment entirely.

We've been seeing some reports about Angular DevTools being unable to detect applications running in dev mode.
This commit adds more context to the error message displayed when development mode is not detected and offers some possible resolutions.
Displays 3 common reasons why DevTools fails to detect an application running in dev mode. Links directly to angular.dev for relevant configurations.
Links to the Angular DevTools issue template if none of the suggestions work.

Previously, when "Hide injectors with no providers" was toggled, it is possible for the injector tree visualizer to have no Element injectors to visualize. This caused a bug in the slicing logic that splits apart the environment and element injectors from DI resolution paths within the injector tree component in Angular DevTools.
Now, this logic is correctly handled when there are no element injectors to visualize.

This change is a proof of concept of how the new Chrome DevTools
Performance extension API (https://bit.ly/rpp-e11y) can be used to
surface Angular runtime data directly in the Chrome DevTools Performance
panel.
Specifically, it implements the following changes:
1. Use the profiling status notification API to toggle the Timing API:
The notification API is implemented under the
chrome.devtools.performance extension namespace and consits of two
events: ProfilingStarted and ProfilingStopped, dispatched when the
Performance panel has started and stopped recording, respectively. This
API is used to enable the Timings API when the recording has started in
the Performance panel and disable it when recording has stopped.
2. Use the User Timings `detail` field format specification of the
Performance extension API
(https://developer.mozilla.org/en-US/docs/Web/API/Performance_API/User_timing)
to inject data collected by the Angular Profiler into the
Performance panel timeline. Angular Profiler uses several hooks to
measure framework tasks like change detection. With this change, this
measurements are visible in the same context as the runtime data
collected by the browser in the Performance Panel timeline.
Note: to enable the user timings to be collected in the first place, one
needs to open the Angular DevTools panel so that the related artifacts
are loaded in the page. This shortcoming can be fixed in a follow up so
that the extra step isn't necessary.

This stamping is interfering with publishing to the Firefox addons store by brining in the entirety of the `.git` directory as part of the source code necessary for a reproducible build, which Firefox requires as part of it's approval process.
In it's place, we are now using the extension version pulled from the manifest.

Angular DevTools depends on many modern Angular features in order to function. As a result, at present the last officially supported version is v12. Angular DevTools may function for some Angular 9, 10 and 11 applications, but they are not officially supported.
This commit fixes an issue where DevTools would not inject a backend script into an Angular application if it detected it was below version 12. This backend script is important because it's used to inform the DevTools panel that the inspected application is in fact Angular, but that it is not on a supported version.
Angular 9, 10 and 11 applications that successfully have Angular DevTools initialize will now have a red highlight and tooltip on their version number, informing the user that they are using Angular DevTools on a version of Angular that is no longer supported.
Angular DevTools for applications that are below version 9 will continue to display the "Angular Devtools supports Angular versions 12 and above" message.

Previously, a race condition could cause DevTools to enter a state where it can't detect an application on reload. This was caused by a sequencing issue between the content script connection, the devtools panel connection and an event "backendReady" that lets DevTools know when a particular frame is ready to be inspected.
This commit replaces the previously stored backendReady boolean with a promise, so that the devtools panel can eventually run a callback to connect to a content script when that content script emits it's backendReady message.

In the Angular DevTools Chrome DevTools page:
- Angular DevTools is able to ask the background script to list each frame that has been registered on a page.
- Angular Devtools is able to ask the background script to "enable" the connection on a particular frame. This enables the messaging between the content script <-> background script <-> devtools page
- Implements detection of non unique urls on the inspected page
Limitations:
- The `inspectedWindow.eval` API is only able to target frames by frameURL. This means some features that integrate with Chrome DevTools like inspect element and open source will not be available when inspecting frames that do not have a unique url on the page.

The version of rxjs used to build the repository has been updated to v7.
This required only minimal changes to the code. Most of which were type
related only due to more strict types in v7. The behavior in those cases
was left intact. The most common type related change was to handle the
possibility of `undefined` with `toPromise` which was always possible with
v6 but the types did not reflect the runtime behavior. The one change that
was not type related was to provide a parameter value to the `defaultIfEmpty`
operator. It no longer defaults to a value of `null` if no default is provided.
To provide the same behavior the value of `null` is now passed to the operator.

Enabling `strict` is part of an effort to improve the quality of the devtools code base.
One of the direct side effect is to enable `noImplicitAny`, `strictPropertyInitialization` and `strictBindCallApply`.
This commit also replaces `fullTemplateTypeCheck` with `stringTemplates`.

Implements a feature allowing users to visualize multiproviders as one row in the providers table.
Also enables the user to log to console any provider in the table. This log includes information about the provider selected, the injector it was configured in, and also calls `Injector.get(Token)` to determine the value the provider evaluates to in it's injector.

Previously this was the only page that used the inspector, so we automatically changed the tab out of convenience.
Now, the injector tree tab also does uses the inspector for some functionality, so we disable this behaviour.
