Browser-mode visual regression flake: hover state appears in screenshot only during full-suite run

[stevegreco]

I have noticed some flaky tests when utilizing the visual regression testing. It seems like some sort of pointer event or hover state is leaking between tests. I have a component, lets call FooBar, when I run my tests for only that component, they work 100% of the time.

The issue is that if I run the full test suite, they will sometimes fail. Some of the elements will have their hover state activated. It seems like the test is spinning up and just automatically hovering one of the elements on the screen. This only happens when running multiple test files at once, and not when running just the individual file.
