Steps to replicate the issue (include links if applicable):
- in a Wikibase Cloud instance, create a property Y with datatype quantity and two items X and Z (potentially both can be empty)
- open the QuickStatements of this Wikibase Cloud instance and start a batch with one command, trying to add to item X the property Y with value 1 and unity of measurement Z
What happens?:
- the command results in an error; hovering on the error the message "Illegal value: _URI of the unity of measurement Z_" is displayed
What should have happened instead?:
- the command should be executed correctly, resulting in one edit to the item X adding the property Y with value 1 and unity of measurement Z
