test case that crashes

Specifying 'text-rendering: optimizeLegibility;' on a block-level element (<p>) causes Safari 5 to crash when the block element has margins specified with the 'ex' unit.

Like this:
p, dt, dd, li {text-rendering: optimizeLegibility;}
p {margin: .5ex 0 0;}

If 'text-rendering: optimizeLegibility;' is specified on the root element or the parent block, the crash doesn't happen. This has been repro'd on XP and Vista.
