143199 - Hidding / Showing sections of the does not trigger complete page refresh/repaint

Status: RESOLVED DUPLICATE of bug 111379

(Core :: Layout, defect, P3)

Description

[Joshua Gertzen]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.0.0+)
Gecko/20020508
BuildID:    2002050807

Visit the referenced URL and click on the heading "What's new?", this will
collapse the text section below it.  Then click on it again to expand the
section again.  The problem that you will notice is that the the first letter of
the headings below it will get misaligned.  i.e. the heading "What is the
Document Object Model?" will be missing the "W".  This seems to be a repaint /
refresh issue since switching to another application and back again results in
the page being painted correctly.

Reproducible: Always
Steps to Reproduce:
1.Click the "What's new?" heading - the section collapses
2.Click "What's new?" heading - the section exapands


Actual Results:  You see the "W" missing from the "What is the Document Object
Model?" heading.

Expected Results:  The page should invalidate the entire visible painting
surface so that it is repainted after collapsing or expanding a section.
