Does this affect any real-world site?

The change looks good, but you should be able to make a LayoutTest as a repaint test or a ref test.

Sorry for the delay.
I made a ref-test instead of a manual test.

r+ but please improve the test and investigate the EWS failures.

100ms is a very long timeout for a test; you should be able to use 10 or less.

EWS failures are still remaining. I am investigating it.

The ref-test was not working correctly in MAC-WK1, so I added a text repaint test instead of the ref-test.

I'm sorry, r+ was canceled by my mistake. Could you please give r+ again?
