Steps to reproduce:

Open https://bpasero.github.io/firefox-window-open/ and observe the console for a "unload" message.

The sourcecode is available here: https://github.com/bpasero/firefox-window-open/blob/main/index.html

Actual results:

The window "onunload" event fired.

Expected results:

No unload event should have fired. Chrome and Safari do not fire this event.

If the code changes to "window.open("", undefined, "width=800,height=600");", the event is not fired.

The Bugbug bot thinks this bug should belong to the 'Core::DOM: Events' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.
