The `SharedStylesHost` class has been refactored to both reduce the runtime
code size and also modernize some of the code structures. The class is also
adjusted to better support reuse via subclassing or other reuses in the future.
Additional comments have been added to improve readability as well.
The code reduction in a prerelease newly generated Angular CLI application
for production is ~410 bytes.

js_expected_symbol_test
This folder contains tests which assert that most of the code is tree shaken away. This is asserted by keeping gold files of all symbols which are expected to be retained. When doing renaming it is often necessary to update the gold files; to do so use these scripts:
yarn run symbol-extractor:check
yarn run symbol-extractor:update
