You need to wrap calls to these in ASSERT_NO_FATAL_FAILURE.

Done.

Why is this sending to ash?

These are very high-level integration tests that are meant to simulate a user
pressing keys, including system-level shortcuts. The keys need to get routed to
whatever window has focus or whatever module would normally intercept that key,
not necessarily to the main browser window.

If you're saying the window doesn't matter, then should it be removed? I suspect
it's needed for some things, in which case you should pass in the right window.
