I think you fixed this in #16578 ?

[guerler]

This is still an issue, the fix I suggested was to restore the previous working condition but it was suggested to instead apply a fix which does not require copying the entire dict in order to restore reactivity which makes sense. This however has not been implemented yet.

I can no longer reproduce this on dev.
@guerler could you please post an updated clip, if you can still reproduce this?

Fascinating, yes it does actually seem to be resolved. Might be related to the removal of the final legacy chunks related to the backbone-based form mechanism. Thank you for taking a look!
