188165 - caret gets stuck at invisible whitespace between tags

Status: VERIFIED WORKSFORME

(Core :: DOM: Selection, defect)

Description

[Jesse Ruderman]

The caret gets stuck after the space between "foo" and "bar" in the HTML
<p>foo <b> <i>bar</i></b></p>

Neither right, ctrl+right, left, nor ctrl+left can get past an invisible "wall"
just after the space.  I noticed this on mozilla.org, where the caret gets stuck
just before italicized links in articles.  (On mozilla.org, the tags involved
are <a> and <i>.)

This bug only happens when there is whitespace both before and after the <b> --
that is, when the whitespace after the <b> is invisible.  This bug affects both
composer and caret browsing.

This is the same problem I reported in Bug 130889, comment #3.  Happily, my 
fix given in comment #4 still works.  (In 1.4a, it's line 4235 in nsFrame.cpp)

Yes. The testcase also WFM on a recent OS X build. Resolving WFM.
