Even if this is a valid use case (which I'm not sure it is), I don't see that we should do anything different based on whether ot not the parent is snapped.

Yes, if there is a complex case of layout that needs this, then it would be a good argument for adding this method. What I would want to see first, though, is an actual use case -- not a theoretical one -- that needs this method, and uses it in a way that shows it to be a generally useful method to add to the API. ------------- PR Comment: https://git.openjdk.org/jfx/pull/1190#issuecomment-1710862459
