Composite question: The "Other" value and comments are stored outside the object produced by the question

T21680 - Issue with Composite Question: "Other" Value Not Included in the Composite Object
https://surveyjs.answerdesk.io/internal/ticket/details/T21680

---

When a survey stores Other values in a separate field in a survey response (the default behavior), a composite question's value appears as follows:

{
   'contact-information': {
      'text-question': 'some value',
      'dropdown-question': 'other'
   },
   'contact-information-Comment': 'some value'
}

However, this doesn't aligns with a customer's expectations. The user requires to store a comment value within a question's response, as follows:

{
   'contact-information': {
      'text-question': 'some value',
      'dropdown-question': "other",
      'dropdown-question-Comment': "some value"
   }
}

However, there is a problem with restoring a composite question's answer in this case. Neither of the above responses works. Please check the following demo: View Demo. You'll see that the Other item remains empty.

Please elaborate on this usage scenario.
