Strange performance behaviour related to <span>

Hi!

I've stripped down one testcase to a sequence of simple HTML snippets.
Try

(for i in $(seq 1 20); do echo '<div style="float:left"><div></div><div style="display:table"><span></div></div>'; done) > tmp.html; dillo tmp.html

and the development version of dillo hangs for a while. You may vary
the number (second argument of seq).

If you look at the file tmp.html, you'll notice that it is incorrect
HTML. Interrestinly, leaving the <span> away still results in
incorrect and deeply nested HTML, but dillo is much faster:

(for i in $(seq 1 20); do echo '<div style="float:left"><div></div><div style="display:table"></div></div>'; done) > tmp.html; dillo tmp.html

Dillo 3.0.5 is fast in both cases.

Does anyone have an idea what effect the <span> has?

I've already run gprof, but the result does not look very meaningful
at a first glance.

Sebastian
