Great news! Yes, there is an issue tracking that. Martin Fox helped to prepare a solution for this and a PoC that it does in fact work, but because of quite big changes needed for performance improvements I didn't have too much time to actually implement that fix. I'll let you know once that's resolved for one more quick test if you'll have time for it.

The only thing that behaves differently is the translucency with the UNIFIED stage style, but I believe you are already aware of that.
