Adding image if layouter is widen and set as slider

This has been broken since Layouters first appeared and it’s still not working.

I’m trying to add a Lottie file to each Item in a Layouter Slider and am experiencing the same problems trying to get content into an Item other than the first one. It just does not work.

~ Re-ordering Items doesn’t work, Items can’t be dragged / dropped successfully.
~ Layers & Inspection panels do not correlate on Items ordering.
~ Impossible to Copy / Cut / Paste a Lottie container to an Item, it either jumps to the parent container or doesn’t Paste at all.

Am I missing something, or is this Layouter Slider functionality just completely broken & no one is interested in fixing it?

Extremely frustrating…
