Steps to reproduce

[LegacyWindowAlias] extended attribute in WebIDL


Change for WebIDL:


EdgeHTML exposes webkitURL in window, like Chromium and WebKit, but in a different way. The test fails because the property is enumerable in EdgeHTML. (I haven’t checked if there are other differences, but the test checks the relevant aspects.) This should be changed to follow the requirements for LegacyWindowAlias to be interoperable with Chromium/WebKit.
Result in Edge for /url/interfaces.any.html:

URL interface: legacy window alias  FAIL    assert_false: webkitURL is enumerable expected false got true
