Middle click on Windows 10 App doesn't work (again)

I see just old threads and the same problem with metro apps which was fixed two years ago but we have it again. It works on regular programs but with windows app (like calculator) it does nothing. Looks like "close" action really works as "show".

I'm using MMB to close but all other options don't work as well (besides Windows default).

Windows 10 Pro (1607), TT 5.2.1
