The TVML JS element nowPlayingMenuItem shows black screen with tvOS 11.3 (15L5198d) and earlier betas. I have a bug report for this here but i fear it will not be fixed before the release. What can i do?

In Xcode debug log i see this:
Presenting view controllers on detached view controllers is discouraged <TVPMusicNowPlayingViewController: 0x7f918b1a2800>.

The presentation happens automatically by the nowPlayingMenuItem and not by my code, it looks like an internal error.
I just use the nowPlayingMenuItem element and it worked like a charme before with tvOS 11 until 11.3 beta:
