Bug 1891934 - [popover] Handling focus naviagtion when invoker is not focusable. r=smaug

Browse source 
At popover navigation bug 1856539, we left the case that when invoker is not focusable to its default behaviour.
At https://github.com/web-platform-tests/wpt/pull/45391, it is suggested that we should another element next to
the invoker to focus.
