How to debug why draggables don't fire (unless triggered by hot reload)

[Heilemann]

I have a fairly complicated setup, so reticent to create a replica unless I have to, but it does work, and regularly, but it requires a hot reload triggered by code change (not sure about the exact circumstances yet) to get initialized. When first loaded it's simply inert. The components all render, etc. though.

The only thing I've found that I can do to 'fix' it, is to turn my one sortable context off. Then the other drag/drop stuff works just fine on first load.

How do I go about debugging this? What should I look for? I'm perplexed :S
