Field-width of structure breaks when used as extension in blueprint

I have a blueprint that uses an extension like this:

blueprint:

    ...
    fields:
        qcheck: 
            extends: fields/questions

questions:

questions:
    label: Questions
    type: structure
    fields:
        value:
            label: Value
            type: text
            maxlength: 20
            required: true
            width: 1/4
      qtext:
            label: Question text
            type: text
            required: true
            width: 3/4

So the value-field takes 1 quarter of the available width and the question text-field extends to 3 quarters.
When I add a new value/question-text record, the form is displayed correctly (1/4th - 3/4th). But when I click add, the list of value/question-text records has both columns with a 50% width.

Is it possible to tell the panel to keep the layout of the form?

Thank you for the help.
