Unmarked Crossing nodes added by iD are missing tags

[une-abeille-osm]

Describe the bug
When drawing in sidewalks as separate ways, it's necessary to draw crossings as ways as well. Unmarked Crossing ways (as named in iD; crossing=unmarked, footway=crossing) that cross a street prompt the user to connect the ways with a node, and that resulting node has incomplete tags. This results in the user having to manually correct each error before uploading changes.

Marked Crossings and Crossings With Pedestrian Signals do not have this issue.

To Reproduce

1. Draw an Unmarked Crossing way across another way
2. Click "Connect using a Crossing" as suggested by iD
3. View Issues console

Expected behavior
The added node should have all required tags

It sounds like this will be solved by openstreetmap/iD#9586 (review)

You might also want to check out #1201 (comment) where I refactor the crossing presets.

Lets keep this open until openstreetmap/iD#9586 is merged.
