Bug 1484826 [wpt PR 12577] - Don't allow popups during page unloading times., a=testonly

Automatic update from web-platform-testsDon't allow popups during page unloading times.

Precisely, this disallows them when the event loop's
termination nesting level is nonzero.

This is now part of the spec,
https://html.spec.whatwg.org/#apis-for-creating-and-navigating-browsing-contexts-by-name

> The window open steps, given a string url, a string target, and a string features, are as follows:
> 1. If the event loop's termination nesting level is nonzero, return null.
