Disable media control overlay in inprivate browsing

Deleted I was able to disable the media being displayed on the volume by setting the flag edge://flags/#hardware-media-key-handling, Steps I did to verify behavior -

1. From within Edge Insiders, Settings and more, New InPrivate window.
   1. I'll reference this as Desktop #1.
2. From within the InPrivate window, I picked a streaming service (I used both Netflix and Hulu)
3.  Started a video, used keyboard to change volume
   1. From within Desktop #1 Edge Insider, changed volume, I see media info
   2. On lock screen, change volume, I see media info
   3. From Desktop #2 change volume, I see media info
4. Set the flag edge://flags/#hardware-media-key-handling from with Edge Insider on Desktop #1, restart Edge for change to set, kick off InPrivate session and stream media
   1. From within Desktop #1 Edge Insider, changed volume, I see no media info, just volume bar
   2. On lock screen, change volume, I see no media info, just volume bar
   3. From Desktop #2 change volume, I see no media info, just volume bar

As you know, InPrivate browsing enables you to surf the web without leaving a trail, information is discarded when you end your session. This is different than keeping a device secure, or configure privacy settings, when someone has physical access. 

Maybe the ask is this - when using InPrivate browsing, you would like Edge to trigger the edge://flags/#hardware-media-key-handling automatically?
