Yes.

Then maybe some assumptions have been broken, e.g. some actions may be not synchronous in browser_side_navigation_interactive_ui_tests.

Thank you for taking care of the flakiness. I will work with guys who are working on browser-side navigation to investigate the root cause.

Only disable ShortcutsShouldTakeEffectInJsFullscreen when IsBrowserSideNavigationEnabled()

So far this test is only flaky on Linux when IsBrowserSideNavigationEnabled(),
we should not disable it entirely on Linux. So this change partially enables the
test to track its flakiness when browser-side navigation is disabled.
