What's Wrong?

The tool declaration states:

Users will always be able to select "Other" to provide custom text input

However, specifically for "preview feature" type of questions--when options includes a markdown field (triggering the preview layout)--the "Other" / "Type something" option is not presented to the user. So, the only way to choose "neither" is to halt the whole interview with "Chat about this".

What Should Happen?

Expected: "Type something" is available as an option regardless of whether the preview layout is active.

Actual: "Type something" is absent when preview layout is triggered for a question.

Additional Information

Good thing the answers to already addressed questions in the same interview are preserved with "Chat about this".

Also the "Notes" from this type of questions with preview are not being present in the post-interview summary; however, the notes themselves are readable to the model no problem (just a nonfunctional UI inconvenience/nonconsistency).

This new "with preview feature" type of questions is in fact awesome, just needs ironing out.
