Interesting, yes you're right, because the data_items are detached from the parent container, the templateRowMap has no awareness of them and so can't respond to set_local actions correctly.

Ideally we would probably want to intercept those set_local actions within the loop and convert them to set_item, however doing so would also mean having to reverse-engineer what property the component is reading from the item loop when assigning a value. So for now I think just ignoring the set_local action is fine, relying on the data_items list as source of truth.

I think probably better to handle this from data_items component itself, I've opened up #2706 to do so and will close here
