Accessibility and UIA Support #15325
Description
When we hover on the Xaml Button hosted in the childsitelink the UIA asks which element is under the screen point and calls intoCompositionRootAutomationProvider::ElementProviderFromPoint -----> which calls into RootComponentView::UiaProviderFromPoint ----> RootComponentView::Hittest and then it tries to find the tag for the ContentIslandComponentView.
As ViewComponentView is the base class for ContentIslandComponentView it should correctly return the tag.
Once the above is implemented ensure Accessibility props are read in Accessibility Insights.
