Reviewed by Sihui Liu and Megan Gardner.
When the main frame process is receiving the message
WebPage::potentialTapAtPosition, it transforms
the provided root view position if the position is inside a remote frame. This
transformation is
done in RemoteFrameGeometryTransformer::transformToRemoteFrameCoordinates by
calling
LocalFrameView::absoluteToChildFrameOwnerLocalTransform. However, this
transformation only works
if the provided remote frame is a direct child of the local view stored in the
object.
We can use FrameView::convertFromRootViewAcrossIsolatedFrames which handles
this case as well.
