For a question of type `checkboxes`, a checkbox item that is both `checked` and `disabled` should be included in the answers
In this function:

if a choice is disabled it will never be part of the question's answers, even if it is also checked.
This is inconsistent with common behavior. Checkboxes can be both checked and disabled.
I'm surprised I didn't find anything related to this because I think it is quite a common use case. The case is when you want to have some choices forced to be selected by previous answers (but you want to make this clear to the user and avoid the less UX-friendly alternatives like using validation or fixing the answers in the background).
The fix is easy (simply remove the !disabled condition) but I suspect this would break usage that relies on this expectation. Perhaps base the implementation on a configuration option that is off by default :-?.
BTW: the rendering in such cases is also not very nice (no difference between checked && disabled and only disabled) but this can be worked around because of the message we can provide in disabled, e.g. using something like "Required" vs. "Invalid option".
Hey, thanks for opening this issue. Looks like a valid use case.
Given you already figured out the solution, would you mind sending a PR? Feel free to also explore UI options.
