[BUG] No way to expand collapsed input when text is typed directly (not pasted)

What's Wrong?

When entering a long message directly into the input box (e.g., via a voice-to-text tool like Typeless), the content gets automatically collapsed/folded once it exceeds a certain length.

The Ctrl+V Ctrl+V (double press) shortcut to expand collapsed content only works for pasted text. If the text was typed or dictated directly into the input field, there is no way to expand and review the full content before submitting.

What Should Happen?

There should be a way to expand any collapsed input, regardless of whether it was pasted or typed directly.

Steps to Reproduce

1. Use a voice-to-text tool (e.g., Typeless) to dictate a long message directly into the Claude Code input box
2. Observe the input gets collapsed after reaching a certain length
3. Try pressing Ctrl+V twice — nothing happens because no paste event occurred
4. There is no other shortcut or UI element to expand the collapsed content
