Could you perhaps explain in the changelog why we need rebaselines, or what the
test diffs look like?

After the latest patch iteration I see real failures in 
fast/text/emphasis-complex.html, fast/text/emphasis-ellipsis-complextext.html
for emphasis marks over Arabic text, indicating there might still be something
wrong.

fast/text/complex-preferred-logical-widths.html has a somewhat suspicious length
difference, originating from a difference in the space before the word "lines",
as much as I can tell. Any idea what the reason might be?

There seem to be some +1/-1 differences in vertical selection ranges, too - are
these safe?
