pagehide, visibilitychange, beforeunload ALL broken when navigating away or closing either the tab or window/app rendering navigator.sendBeacon useless

We need to get this sorted. More and more developers rely on live up-to-date analytics on user activity and knowing "when" a user has navigated away has to be by definition a major part of it.

pagehide, visibilitychange, beforeunload do not have any effect whenever the user navigates away (by inputting a new url, using back/forward, using favorites, closing current tab or window)

All other major browsers support this. 

What is going on?

Thanks for the report.
It would be cool if you had a minimal testcase, that the WebKit Team could work with.

All of these events are implemented, and many dozens/hundreds (if not thousands) of automated regression tests demonstrate they're working as expected.

Karl asked for at least one reproducible test case here https://bugs.webkit.org/show_bug.cgi?id=263326#c2

If you could provide step-by-step instructions on what to look at, we can explore what's going on in that case!

Gentle ping.

For the above stated reasons, there's little progress we can make here without a concrete example.
