As with regular Angular components, Angular elements are expected to have their views update when inputs change. Previously, Angular Elements views were not updated if the underlying component used the `OnPush` change detection strategy. This commit fixes this by calling `markForCheck()` on the component view's `ChangeDetectorRef`. NOTE: This is similar to how `@angular/upgrade` does it: https://github.com/angular/angular/blob/3236ae0ee118d0734c90fa9f3767435396213470/packages/upgrade/src/common/src/downgrade_component_adapter.ts#L146. Fixes #38948 PR Close #39452
