Details

(Keywords: css-moz, Whiteboard: need to rewrite titledbutton to use pseudo-style)

turn on paint flashing, mouse over a gfx scrollbar (like in bookmarks window) and you'll see the whole tree reflow/repaint. this is happening because the :hover rule for each component of the titledbutton sets the list-style-image property in CSS. While the titledbutton code can tell that the new image is the same size as the old one and only a paint is needed, the style system assumes a reflow is needed.
