What's Wrong?

When using the AskUserQuestion tool and selecting the "Other" option to enter custom text, the submitted text is not fully visible in the chat UI after submission.

Actual Behavior

The submitted text is truncated or not fully shown in the chat UI. (Note: the agent does receive the full text correctly — this is a display-only issue.)

What Should Happen?

The full text entered in the "Other" field should be visible in the chat history after submission, just like regular chat messages.
