Hey Dennis, I'm back with sort of an involved ask from the team.
[EDIT: But first, could you try restarting the browser and see if this is fixed for you? If so, feel free to disregard the rest of this. This is an involved multi-part issue so if this is fixed with the restart you won't be hitting the case we need the trace for.]
If you're comfortable doing so, this trace would really help investigate what's going on here.
Close all instances of Edge by going to the App menu and clicking Close Microsoft Edge (This ensures all browser processes are closed.) It’s important that there are no running msedge.exe processes. Open task manager to double check, and make sure you aren't set to keep running Edge in the background!
Open a command prompt as administrator.
Run
tttracer.exe -children -out %userprofile%\desktop\msedge_trace %programfiles(x86)%\microsoft\edge\application\msedge.exe --no-sandbox
You theoretically should see this issue in Stable as well, but might need to edit that run path to the Edge Dev version.
Once you see a repro, close the browser and zip the traces which will be left on the desktop. (These can be very large so I suspect even with zipping it TC won't let you attach it. Sharing via OneDrive can be helpful, or another hosting site as you prefer.)
Thanks so much, we've got several teams digging in on this and getting this trace would be hugely helpful.
