Thank you Adam for taking the time to create this ticket, and for linking adequate resources to do proper triage.

I'm accepting on the basis that this makes sense but I would like to see more research being done regarding what to use to replace unload. The linked MDN docs say:

The pagehide event is sent to a Window when the browser hides the current page in the process of presenting a different page from the session's history. For example, when the user clicks the browser's Back button, the current page receives a pagehide event before the previous page is shown.

Is not immediately clear to me that this is a good replacement. From ​these Chrome docs we may need to evaluate visbilitychange as well.

    10 The [https://github.com/fergald/docs/blob/master/explainers/permissions-policy-deprecate-unload.md linked proposal] points to [`pagehide`](https://developer.mozilla.org/en-US/docs/Web/API/Window/pagehide_event) as a more reliable alternative, which seems like it would be compatible with the goal of closing child popups.
