Selecting all machines in a state in the UI causes traceback in backend

[Alberto Donato]

If I click the checkbox to select all machines in a state (e.g. New or Ready) in the UI, I see a traceback like this in the backend, with a validation error:

2022-09-29 09:30:34 maasserver.websockets.protocol: [critical] Error on request (34) machine.list: {"status": ["Select a valid choice. =ready is not one of the available choices."]}

After this, no action can be performed on the selection (all entries are disabled)

This seems to be fixed for the frontend with the backend fix. Is this still an issue in MAAS 3.3+?
