border-widths shouldn't be layout-dependent.

In the following test-case:
<!doctype html>
<div id="inline" style="display: table-row; border-top: 10px solid red">A</span>
<pre>
<script>
document.writeln(getComputedStyle(inline).borderTopWidth);
</script>
</pre>
We return zero but other engines just return 10px, which is the computed border.
https://drafts.csswg.org/cssom/#resolved-values doesn't list border widths, so we're on the wrong here I think.

They're not listed in https://drafts.csswg.org/cssom/#resolved-values.
This matches other engines as well.

A few tests failed with this, because our used border-width for themed stuff like <button> is theme-dependent. I could fix the tests by using appearance: none, but I think it's unfortunate so I'd like to come up with a better solution if any.

The test-case from comment 0 started returning 10px in Firefox 70 (20190802215241) (Pushlog).
Emilio, do you think this bug was fixed by bug 1404140?

This particular case was fixed by bug 1404140. Appearance can still affect it tho, see this code: https://searchfox.org/mozilla-central/rev/8fd39dc89c68501a354446a8681ec8263d15e5aa/layout/style/nsComputedDOMStyle.cpp#2200
