First failing build: https://ci.chromium.org/buildbot/internal.bling.main/iphone10-simulator-x64/14445
Failure seems to be translate related:
	1   ios_chrome_external_url_egtests     0x00000001061774d5 -[TranslateTestCase testAutoTranslate] + 5669

Only included CL: https://chrome-internal-review.googlesource.com/c/chrome/ios_internal/+/664888
But that is a DEPS roll, so let's look at what's in it:

> git log --name-only 0cd13efcb6b67e59bdc5911226455bab13560167..af5475b887c46f2261cdc098b2e272274e57c9a9

Includes https://chromium-review.googlesource.com/1178691 which is modifying ios translate things.

Going to rollback above mentioned CL, but I think we'll have to wait for a DEPS roll before tests go green.

Thanks. I'll fix the translate test.

[Reland] Replace polling with callbacks in translate_ios.js.

This should alleviate flaky errors when translating on iOS.

When translate is tapped, translate_ios.js polls translate.js to wait
for translate element ready and then later polls again to wait for the
translation result. Polling can often time out due to network slowness.
