This issue has been verified using Visual Studio 17.12.0 Preview 3(9.0.0-rc.2.24503.2 & 9.0.0-rc.1.24453.9). Can repro this issue on windows platform. 8.0.92 works fine.

It seems that this issue is not limited to the Windows platform. On Android, the Shell Flyout menu is locked and does not respond to user input after navigating from a MenuItem page.

Validate on the other supported platforms as well.
