I agree that it is necessary to re-apply CSS to child nodes when the parent
node CSS changes. The issue that I originally reported was that I could see
that child nodes had CSS re-applied more than once. The number of times CSS is
applied is currently proportional to how deep in the scene graph hierarchy the
node is.
When a subtree is added to the scene graph, I would expect that CSS can be
reapplied to each node only once, so long as it is done in a top-down manner.
I could be wrong, I’m not certain how rules relating to sibling nodes might
invalidate that assumption. In HTML there is the concept of adjacent sibling
combinator, e.g. “img + p" for paragraphs that come immediately after any
image. I don’t think JavaFX has anything like that thoughts o top-down should
work out.
