I am *very* suspicious of this change. Yes, it sort of works, but I wonder if
it might backfire as it breaks the contract of show() and also depends on some
assumptions ("The very first show call is just for us to do the correct CSS
processing").
Would it be possible to try the applySceneStylesFromOwner() approach, maybe by
moving the method to Utils to avoid changing the API? This issue does not seem
to be limited to Tooltip - there is a similar code in CustomColorDialog:88 for
example.
What do you think?
