Fix flaky DoubleClickWhenSelectable E2E test (#11586) (#11602)

The test `LegacySelectableTextTest.DoubleClickWhenSelectable` double
clicks on a selectable text. This should register as one click to select
the text and then pass the second click through to the press handler.

However *sometimes* on Windows Server 2022, both clicks get through, which
means the test will fail randomly in CI and/or block unrelated PRs.

This PR changes the test to instead detect when that happens and log a
warning, rather than fail the test and/or disable the entire test.
