a mirror of #317

It is really needed as some mappers are confused and repeatedly damage data as iD is not showing it clearly what is mapped already

Update: See #317 (comment) – please use the preview link in that comment to test out if the merged and proposed change does what this issue is about.

closing as mostly solved, though not in way proposed here (as property, not top-level preset)
