Subject: Fix for CPU-hog bugs with deeply nested elements.

This patch fixes a cpu-hog regression of GROWS2 with respect to dillo-3.0.5.
The problem arises with some deeply nested elements. e.g.:

  (for i in $(seq 1 20); do echo '<div style="float:left"><div></div><div
  style="display:table"><span></div></div>'; done) > t0.html

  (for i in $(seq 1 20); do echo '<div style="float:left"><div></div><div
  style="display:table"></div>'; done) > t1.html

For both, taking away the SPAN or float is much faster.

Note: Some "unrelated" sited (i.e. not clearly hogging the CPU) have been
measured to render near two times faster with the patch.
