Inline editor finds false positive animation name

[jasonsanjose]

@-webkit-keyframes div
{
0%   {top:0px;}
25%  {top:200px;}
75%  {top:50px}
100% {top:100px;}
}

Searching for <div> finds the above animation.

We already had a unit test for this, so I've commented it out with a TODO referencing this issue. (This is rolled into my pull request re-enabling the big suite of CSS parsing tests).

Seems like this could be a starter bug.

FBNC @jasonsanjose now that #1907 is merged.

Confirmed fixed. Closing.
