Bug 21287 – Clean up code that changes newStyle in setStyle()

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Simon Fraser (smfr)]

Various table-related methods muck with the RenderStyle passed into setStyle(). This is evil because
i) that style would be better treated as read-only, and
ii) if someone does a Diff earlier on, their diff gets invalidated.

I don't think we should keep RenderTableSection::setStyle around just to do the assertion.

+        if (e && (e->hasTagName(tdTag) || e->hasTagName(thTag))) {

This new code doesn't affect cases where CSS is used to turn an element into a table cell. But the old code did. Is that OK?
