New description:

 When editing long posts with a fair amount of (nested) HTML tags, browser
 will issue an unresponsive script error when switching from Visual to HTML
 editor.

 Attached are two very long posts, similar except testcase-unresponsive.txt
 has about 2500 extra
 {{{
 <p><br class="spacer_" /></p>
 }}}

 I haven't encountered any problems with testcase-ok.txt.

 Hoping there's something that can be optimized here.
