When producing a listener, the template pipeline does the following in separate phases:
1. Generates all the variables available within its scope.
2. Adds `restoreView` and `resetView` calls if there are any referenced to local variables (e.g. `@let` or local refs).
3. Optimizes away the variables that aren't used.
This means that we can end up in a situation where the references to the variables in the scope no longer exist, but we still enter and leave the view as if they're there which is unnecessary.
These changes add a simple optimization pass that looks specifically for the pattern of a `restoreView` followed by a `return resetView(expr)`. Furthermore, by changing the order of some optimizations, we're able to drop the `getCurrentView` variable as well.
Fixes#66286.
Add support for `@defer`-only blocks (previously, they weren't rendered in the component tree at all); Fix declared blocks section in the details
PR Close#66546
Add the host/container comment node to the `DeferBlockData`. This node can be used as a `@defer` block locator in the DOM tree in the absence of root nodes.

Previously our system only found the first matching symboling to link to within a code block on each line, now we set up a link for all of the discovered symbols on each line
Fixes#65403
Update the skip-to-main-content behavior to focus the <main> element when present, with a fallback to the first heading for legacy layouts without a main landmark.
There has been a bunch of confusion as to how `animate.leave` works on child nodes when the non-animated parent is removed. This section addition should clarify that.
Extends the `focus` method of form fields and custom controls to accept and propagate `FocusOptions`.
This enables developers to control focus behavior more precisely, for example, preventing scrolling when focusing an element.
The Zone.js build was depending on the `--outFile` flag from TypeScript which is deprecated. These changes switch to using `--outDir` and copying the files out of the directory instead.
Previously we were unconditionally setting the control value back into
the value, regardless of if it had actually been changed. This PR
changes the logic to flush the pending sync on touch if there is one, or
just skip it if there isn't.
Currently migrating from `[ngClass]` to `[class]` isn't entirely supported, because `[ngClass]` supports `Set` values while `[class]` ignores them.
These changes add a bit of logic to bring them closer together and make the migration easier.
This PR adds the ability to manually register a binding with the
`FormField` directive. This is useful for a lower-level implementation
that takes the field tree as an `input()` rather than relying on the
automatic binding from `FormUiControl`.
```ts
@Component(...)
class Outer {
constructor() {
@Component(...)
class Inner {}
}
}
```
previous behavior was that IVy transformation was only applied to `Inner`, thus breaking `Outer` transformation.
