anchor-name-inline-001.html passes in Firefox Nightly now per wpt.fyi, so let's narrow this bug to just focus on anchor-getComputedStyle-002.html which still fails the two subtests mentioned in comment 0.

And those are really about anchor positioning in layout, so I'll note that in the summary.

Notably, only the first failure has to do with multicol - the second one is about inline fragmentation, which might be dependent on bug 489100.
