Attached video addressbarflicker.mp4

I've attached a 10% speed video to demonstrate the problem. It sometimes looks like this, where the address bar starts large, then pops down to its unfocused size, then pops back up to its focused size again. Other times it starts at its unfocused size and then pops back once to its focused size. In either case it's noisy.

Is this during startup or also when opening new windows? I guess this is the kind of issues that are likely to regress if we fix them once without adding a test. Maybe a nice way to add a test could be to add profiler markers for code that triggers enlarging/shrinking the address bar, and then have a test that uses the profiler, and checks for the absence of these profiler markers when we expect no change.

The urlbar was changed to no longer expand when opening the new tab page, so this bug shouldn't be relevant anymore.
