Script: response_variable not working in choose-sequence

Hello,

I’m testing around with scripts in Home Assistant and don’t understand what’s wrong.
My problem is the response_variable. If the Script contains a choose-option the answer is empty, but should be filled with the response_variable.

If the script contains no choose-sequence it’s working.

Question: Why does the script not return my value while in choose-sequence?

With this test-script I’m getting a result from the script:

alias: test
sequence:
  - variables:
      limit: |
        {{ {'value': 1200 } }}
  - stop: Done
    response_variable: limit
mode: single

With this script the response is empty.
But it’s no scope-issue, because the notify is filled correctly with the value.
So where I’m wrong?

alias: test
sequence:
  - variables:
      limit: |
        {{ {'value': 1200 } }}
  - choose:
      - conditions: []
        sequence:
          - service: notify.notify
            metadata: {}
            data:
              message: "{{ limit.value }}"
          - stop: Done
            response_variable: limit
mode: single

Thank you for your help.
