Description Chris Dumez 2021-07-23 14:27:07 PDT 
WebKit is the only major browser engine what returns "about:blank" for Location.href in a closed window. Gecko returns the empty string and the property is completely undefined in Blink.

This seems to be causing failures on WPT tests like:
- https://wpt.live/html/cross-origin-opener-policy/resource-popup.https.html

Because the test expects that the URL becomes something else than "about:blank" after closing.

I filed https://github.com/whatwg/html/issues/6899 to clarify the expected behavior.

Our behavior matches the spec. Let's see if we can get the test updated and other browsers to follow.
