Been kinda flaky since https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20Tests%20%28dbg%29%281%29/71600

Errors look like this:

Oops, that link was wrong. Flaky since: https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20Tests%20%28dbg%29%281%29/71565

The test that's failing is WebViewTest.SpatialNavigationJavascriptAPI

Nothing obvious stands out in the blame list. Maybe https://chromium-review.googlesource.com/c/chromium/src/+/1214803 ?

Ok, the test was added in the build right before the first failure: https://chromium.googlesource.com/chromium/src/+/e58c9eecce5de4f6e40017d8554d966a1a85644f

So either the test is flaky from the beginning or something in the following build made it flaky. Since there's no obvious culprits in the following build, I think the test is probably flaky from the beginning.

Going to disable the test.

The following revision refers to this bug:
