Since this was a pretty big CL and revert likely wouldn't land cleanly, I'll mark the test as flaky instead. Please investigate and fix soon.

My CL just changed some names, so it can't be the cause of the flaky. Also the test had been flaky before my change. Anyway I will look into it.

[PE] Deflake paint/invalidation/table/table-hover-on-link.html

The test flakily failed in the following ways:
1. Hover state was not applied and the background was still red. The
   test perhaps finished before the hover state was visualized.
2. The actual result showed net::ERR_FILE_NOT_FOUND. This was perhaps
   caused by the click.

Now
1. Use runAfterLayoutAndPaint() before the test finishes;
2. Remove the click. Just hover.

Also simplify the test and convert it into a ref test.
