Bug 190539 – Window's properties such as 'location' should not become null when it loses its browsing context

• Component: DOM
• Status: RESOLVED FIXED

[Chris Dumez]

Window's properties such as 'location' should not become null when it loses its browsing context. This Webkit behavior is not standard and does not match other browsers.

This doesn't look great.  What's going on here?

It is a progression since location is no longer null. However, we are still failing because the test expects the URL to persist after the window is detached.

We are currently discussing standardizing what the URL should be here:
https://github.com/whatwg/html/issues/3959

Right now browsers behave like so or location.href:
- Firefox and Safari (after this patch): ""
- Edge: "about:blank"
- Chrome: undefined

The test's check would fail in all browsers.
