Fixes #13642

Summary of the issue:

In Firefox, pressing enter on a list item in an editable region does not switch to focus mode.

Description of user facing changes

NVDA will switch to focus mode when pressing enter on an editable list item.

Description of development approach

Restricted the cases in which NVDA will drop the controlTypes.State.EDITABLE to exclude objects with a role of controlTypes.Role.LIST and LISTITEM.

Testing strategy:

Tested using the test case given in #13642. Tested in a Google sheet with Braille mode enabled to make sure this does not regress changes implemented in #7935.
