Bug in select selector ui?

In have an automation blueprint with a select selector with multiple: true and custom_value: true.
When i add an automation based on the blueprint and want to add custom values, the selector is misbehaving i think. When entering text, the selector looks for matching predefined options and after some seconds reset the input field. Everything entered until then is gone.

I’ve tested this in Firefox and Edge on Windows and the companion app on Android.

blueprint:
  name: select-selector-ui-test
  domain: automation
  input:
    meldung:
      name: custom multi select
      description: Multiple selections and custom values
      selector:
        select:
          multiple: true
          custom_value: true
          options:
            - label: this is option one
              value: option1
            - label: this is option two
              value: option2
            - label: here we have option number 3
              value: option3
            - label: last but not least number four
              value: option 4
