Open the attached test page and wait a couple seconds. Soon the search field will animate. The input type='search' placeholder text shakes up and down during animation. The jittering does not occur if you remove the "type=search".
It looks like this is a regression caused by r90089.

Better test case
Made a better test case, with both search and text fields. It has something to do with specifying both left:0 and right:0.
Thank you for the report. I'll take a look at this next week.
The value also shakes.

It's possible that this patch will change the behavior of the test though I had no difference on Mac.
I'm landing the patch with a test_expectation.txt adjustment, and will see the bot results.
