24763	JOSM doesn't warn about many moved nodes	GerdP	team	"==== What steps will reproduce the problem?
1. Download area with 20 or more buildings
2. Perform search for `allindownloadedarea`
3. Use mouse to move the selected objects
4. Use short cut like Shift+left to move the selected objects

==== What is the expected result?
Both step 3 and step 4 should trigger a warning about many moved objects
==== What happens instead?
Only step 3 produces the warning
==== Please provide any additional information below. Attach a screenshot if possible.
The check is implemented in `SelectAction.confirmOrUndoMovement()`. It is only executed when the mouse is used to move objects.
