These tests are timing out. Maybe we should just increase the timeout limit in ios/build/bots/scripts/test_runner.py.

smut@ - Assigning to you since you added this file recently.

I don't think we should increase the timeout, that would mask the real issue that this test appears to flakily hang. It's expected to take a few minutes at most.

Here are some logs where the test hung with no output until Swarming killed it after almost 20 minutes:

I've changed the way how LoadHtml works, which is the reason of flakiness. I've already decreased lolling interval, which could fix the problem. If the tests are still flaky then I will change load state polling to waiting for navigation callbacks.

[ios] Fixed WebTestWithWebState::LoadHtml flakyness.

Polling for PAGE_LOADING loadPhase is flaky because the phase can
quickly change to PAGE_LOADED in the same runloop cycle. Use
WebStateObserver to wait until navigation is committed instead.

[ios] Reload the page inside WebTestWithWebState::LoadHtml if necessary.

Reload the page if script execution fails. Page reload was performed
for data URLs and looks like it's also needed for loadHTML:baseURL: API.
