Choosing an option in the Status dropdown for bulk assignment doesn't change the dropdown button

As seen here (Closed is chosen in the Status dropdown):

To reproduce:

  1. Go to Issues for a project
  2. Select multiple issues
  3. Open the Status dropdown and set the Status to "Closed"
  4. Note that the dropdown button itself hasn't changed, despite an option being selected

This works fine with the other dropdowns, just Status doesn't work correctly.
