Make midi preview to follow project root key


I’d like to preview midi files in mediabay in project key.
It works pretty easy with audio files - when audio file have root key setted in media bay and project root key is selected too - I use “Align beats to project” in Mediabay, and audio preview is matched to projects root key.
So, I thought the similar should be with midi files. But it doesn’t changed key for midi.
Also - I see that midi Key is setted in mediabay, while when I d&drop this midi to track, I can’t see it’s key in info line (as in with audio files).

So my question is: how can I make Cubase see midi key and match it with project root key while previewing in mediabay?
