Add a specific test case to ensure the keybinding migration properly
deletes the deprecated 'targetSelector' property after migrating to
'targetElementId'. This test provides additional coverage to verify
the migration doesn't leave behind obsolete properties.
The test verifies:
- The old 'targetSelector' property is removed
- The new 'targetElementId' property is added with correct value
- Other properties remain unchanged
