This doesn't trip on any layout tests. I'm going to see if I can trigger it
manually ...

I don't think this can happen now, any hit that would hit a PseudoElement is
always retargetted at the parent node. See the code in here checking
isPseudoElement().

Done. I removed the m_isFirstLetter variable since it wouldn't be needed anymore
which simplified this function a bunch.
