AskUserQuestion: speech-to-text input in 'Other' field not registered until option is toggled

Bug

When using AskUserQuestion (with multiSelect: true), selecting "Other" and using speech-to-text to input custom text, the pasted text is not registered or displayed in the response.

Steps to reproduce

1. Claude presents an AskUserQuestion with multiSelect: true
2. User selects "Other" to provide custom input
3. User uses speech-to-text (macOS dictation) to input text into the custom field
4. User presses Enter to submit

Expected

The speech-to-text text is included in the response and visible in the conversation.

Actual

The speech-to-text text doesn't show up in the submitted response. The user has to:

1. Press Enter (submits without the text)
2. Deselect "Other"
3. Reselect "Other"
4. Only then does the previously dictated text appear

It seems like the input field doesn't register the value from speech-to-text/dictation paste until the option is toggled off and on.

Environment

• macOS (Darwin 25.2.0)
• Claude Code CLI
