Privacy Browser PC

This can be demonstrated by going to https://www.stoutner.com/privacy-browser-android/changelog/, shift-clicking on the F-Droid link (which will open a new window and which usually takes a long time to load), and closing the new window while the tab is still loading. Privacy Browser will crash and both windows will close.

This likely has to do with the tab trying to update some part of the UI, like the progress bar, after it has been destroyed.
