Now if you add a new inherited, pref-controlled property, you must
declare whether it can have an effect on scrollbar styles. If no,
then the property will be skipped in the assertions that check
whether our cached styles are equal to those we would compute.

According to this resolved spec issue:
https://github.com/w3c/csswg-drafts/issues/2140,
we retire the 3-valued <position> on
1. `object-position`
2. `perspective-origin`,
3. `mask-position`
4. `circle()` and `ellipse()`
, but still keep the support for `background-position`.
Besides, I simply run this python script to generate the .ini file:
```
s = sys.argv[1] + ".ini"
with open(s, "w") as f:
f.write('[{}]\n'.format(sys.argv[1]))
f.write(' expected: FAIL\n')
f.write(' bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1559276\n')
```

ISSUE-21257: set redirectEnd on PerformanceResourceTiming
<!-- Please describe your changes on the following line: -->
Added the appropriate attribute and setters. Included a Timer struct with a `Drop` function to set this value to zero in error cases. Set the value to `responseEnd` on success. Eliminated tests that now pass.

Clean-up navigation
<!-- Please describe your changes on the following line: -->
1. Navigation as a result of following a hyperlink should be done in a task: https://html.spec.whatwg.org/multipage/links.html#following-hyperlinks:dom-manipulation-task-source
2. The javascript url navigation should also be done in a task: https://html.spec.whatwg.org/multipage/browsing-the-web.html#navigating-across-documents:dom-manipulation-task-source
3. In `window.load_url`, it seems there is no need to send a message to the script-thread(the entirety of `load_url` should instead be done in a task when appropriate), so we can just do that last part "sync" by calling a method on the script, which will send a message to the constellation(for the parallel navigation steps), or queue task(for the JS navigation), as appropriate.
4. Separate the "normal" navigation flow from the handling of "navigate an iframe" message from constellation, since doing everything in one method as was previously done with `handle_navigate`, is confusing.
