Thanks for the detailed ticket and for including a possible solution. I'll take a look at whether I can reproduce this issue as soon as I've finished updating the Windows in my VM.

In general, I don't see an issue with adding the "unload" listener for all platforms as it doesn't seem to do anything we wouldn't want to do anyway.

  • Priority changed from Unknown to P1
  • Ready set

I can reproduce this issue with our development build which, however, still seems to be on Apart from that it also appears in the latest build so I'm setting this ticket to ready.

The development builds for Microsoft Edge are outdated. Our development build automation currently fails due to an issue with manifoldjs that needs to be addressed by Microsoft.
