  27 <p>If a zero lengthed render object (such as a text node that has been set to "") occured at the end of a line, it was previously given a non-zero sized run.</p>
  28 <p>A crash would occur on iteration over a node containing such a run.  NodeIterators, the innerText property, and hovering over a link all use iteration.</p>
  29 <p>This tests iteration using both the innerText property and NodeIterators.  It is successful if it doesn't crash Safari.</p>
