List of steps to reproduce
- go to a random already-existing Wikidata item with a coordinate location (e.g. https://www.wikidata.org/wiki/Q111103620 this cute palace in Trento, Italy )
- goto "coordinate location"
- click Edit
- keep calm, don't do anything else, don't move the map, just do this:
- click on Zoom in (+), or Zoom out (-)
Proof of concept
What happens?:
The zoom button closes the Kartographer picker.
What should have happened instead?:
The zoom button should just zoom.
The zoom button should not close the Kartographer picker.
