Just to clarify, I don't think I said that. :) What I meant was that I
think it should be possible to improve this in Blink / Gecko, _without_
requiring layout. After all, layout isn't going to help that much anyway
(the actual box sizes calculated during layout are invalid for preferred
width calculation, unless they are based on something fixed-sized from
CSS, etc.). It's done as part of layout in Presto, because of some
Presto-specific technical reasons, and those reasons don't apply in
Blink, at least.

While it does affect performance, I too doubt it's significant, but in
any case, like I wrote above, layout doesn't give you the values you're
after anyway (but Presto calculates preferred widths as a by-product,
when requested), so doing a dedicated preferred widths calculation pass
that doesn't lay out should be fine.
