Now Playing Widget Vs Apple QuickLook

Describe the bug
Hi. I'm using the native touchbar "Now Playing Widget" which is working great with Spotify and iTunes. But when I play a video or an audio file using the Quick Look option of macOS (typing the space bar when I'm selecting the file into the Finder) the widget on the touchbar turns to an ugly white rectangle... As soon as I close the preview window (typing the space bar again) the widget goes back to where it was (e.g. the last track played in Spotify).
Is there a way to fix this? I don't know if I'm the only one encountering this as I didn't find any related topic on this forum...
All the best from France,

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Touchbar on a MacBookPro14,2

Device information:

  • Type of Mac: MacBookPro14,2
  • macOS version: 10.13.6
  • BetterTouchTool version: 2.620 (926)

In the latest alpha version it should hide in such a situation. (Quicklook doesn't provide any info unfortunately)

Thanks, I didn't checked alpha changelog before posting... Cheers !
