Description

This PR fixes #5911 by providing an overlay view for ContextMenuHostView while its animations are playing. The overlay view ensures that whenever a message is cut off at the top or bottom of a message, the message slides behind the top or bottom bar respectively.

There is one nit with this current implementation, and its that the bottom bar doesn't retain its visualeffectview for some reason, but its definitely better than the previous UX with the message going on top of the bottom bar.
