Comment (by westonruter):

 In #55491 we're working to remove the deprecated `unload` event handler
 from core. One of the instances was added in this ticket. I tried to
 reproduce the issue in Firefox today (with the Classic Editor plugin
 enabled), and I was unable when the `reload` code from r39282 is removed.
 I take that to mean the Firefox-specific issue was fixed in the past 7
 years. So I'm recommending deleting that code. Nevertheless, if anyone
 knows of a good reason for it to remain, please chime in on #55491.
