Bug? Menu displays over playing content

When starting a playlist of videos via API call, if a peice of content is already playing – the new playlist is loaded but the menu is shown on top.
If the same command is sent when the player is idle – it works properly (menu hidden)

http://localhost:8080/jsonrpc?request={%22jsonrpc%22:%222.0%22,%22id%22:%221%22,%22method%22:%22Player​.Open%22,%22params%22:{%22item%22:{%22directory%22:%22smb://10.20.0.243/videos/%22}}}
This is my call, just asking to play a folder of videos

Can i confirm with someone that this is indeed a bug?
I had been chasing this for a while in my dashboards project – and think ive finally tracked it down to API Calls when the player is not idle.
Reproducible on all my installs here.

Is anyone able to confirm they see the same behaviour?
