WTH: scripts with input variables don't work in Automations ui

Month of "What the heck?!"

If I create a script and it can accept variable inputs, those don’t show up in the automation UI as an optional input.

They do if you set a selector for the field.

e.g.

script:
  my_script:
    fields:
      field_1:
        description: ..
        selector:
          ...
    sequence:
    ...
