| If a zero-length render object (such as a text node that has been set to "") occurred at the end of a line, it was previously given a non-zero sized run. | |
| 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. | |
| This tests iteration using both the innerText property and NodeIterators. It is successful if it doesn't crash Safari. | |
