[BUG] [Mobile app – Remote Claude Code] Multi-line input box expands to fill the screen, keyboard can't be dismissed, making the agent's plan/output unreadable

What's Wrong?

Environment: Claude iOS app, Remote Control for Claude Code (controlling a local session on my Mac from the phone).

When I dictate or type a message longer than ~5 lines, the input box keeps expanding and takes over most/all of the screen, and the keyboard won't dismiss. While a draft is in the box I can no longer scroll or read the agent's plan/response, so I can't review or comment on the plan before answering.

When I try to physically shrink the input box, I accidentally tap other elements (links) that throw me to the full chat history — and the dictated draft is lost in the process.

What Should Happen?

• The input box should cap its height (with internal scroll) so the conversation/plan above stays visible.
• There should be a reliable way to dismiss the keyboard / collapse the composer.
• I should be able to scroll and read the agent's output while a draft is still in the input box.

Error Messages/Logs

Steps to Reproduce

1. Open a session via Remote Control in the Claude iOS app.
2. Dictate or type a message longer than ~5 lines so the input box grows.
3. Try to scroll/read the agent's plan or response while the draft is still in the box.
4. Try to collapse the input box to see the conversation — this causes accidental taps on links, navigating to the chat history and discarding the draft.

Additional Information

This is a UI/layout bug in the iOS mobile app (Remote Control), not the terminal CLI.

Impact: makes it very hard to review agent plans on mobile — exactly when long, considered replies are needed. Combined with the draft-loss in #71605, a single mistap wipes real planning work.

Related: #71605 (draft lost on navigation + keyboard covers the Send button). This report is specifically about the composer expanding and blocking the conversation view.
