4007	Deleting/removing value of a key does not remove the key, but should	AM909	team	"Consistently, deleting the value of a key anywhere in JOSM removes that key entirely. The relation editor in v2255 does not do this, but it should.

If you edit a relation and delete the value of an existing key, the tag is still saved (with an empty value). The tag should, instead, be deleted."	defect	closed	normal		Core	tested	fixed	relation 2255
