Fix assistant hint flickering to action name

This is an attempt to fix #21029 but it doesn't 100% fix it: we only hide the message if the binding isn't available instead of showing the action name. What I don't understand yet is why the binding isn't available in the first place when switching the tab, even though the editor is `focused()`, `within_focused()`, `contains_focused()`. I do think not showing anything is better than showing the action name though, since that's too long.
Remove dead snowflake code (#21041 )
