does it's presence trigger slow (complex) text path which when not present uses fast path? if so, that could explain much

(In reply to comment #1) > does it's presence trigger slow (complex) text path which when not present uses fast path? if so, that could explain much I'm fairly certain this is the case, but the selection bug indicates that the fact that it triggers this change isn't properly understood by all of the rendering code (RenderText::canUseSimpleFontCodePath returns true, for example).
