The first MenuItem can not show up while playing music in background

I meet an issue when I use menuBarTemplate, the first page can not show normally while play music in background, but other pages is able to show.

If the player stop playing, the first page is able to show also..

This issue is not seen in tvos9.0, but issue can be reproduce from tvos10.0 to tvos11.0 beta4.

I wrote a demo to this case. Clone and run xcode project https://github.com/fuzhuo/tvosMenuBarFirstPageIssue

Anyone meet the same issue?

I'm already try fire a bug, hope it got fixed in the tvos11 GM build.
