On certain forms, possibly only in combination with certain other elements, pressing enter in expected locations is no longer submitting the form, but instead changing focus to another field.
Able to reproduce on testwiki with the MOVE dialog:
- Go to a page
- Attempt to move it
- Enter new title and reason, press ENTER in the REASON field
- FAIL: Instead of submitting, the input focus is changing to the namespace selector
