[BUG]

Environment

• Platform (select one):
• [ ] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [x] Other: <!-- specify --> JetBrains plugin
• Claude CLI version: <!-- output of claude --version --> 1.0.83
• Operating System: <!-- e.g. macOS 14.3, Windows 11, Ubuntu 22.04 --> macOS 15.6a
• Terminal: <!-- e.g. iTerm2, Terminal App --> JetBrains

Bug Description

<!-- A clear and concise description of the bug -->
When working with the JetBrains IDE integration, I used to be able to make edits to the proposed changes that Claude shows (on the "reject"/"apply" screen). Recently that has stopped working -- I'm still able to make changes to the text in the "apply" dialog, but any changes I make are immediately undone when I click "apply".

Steps to Reproduce

1. <!-- First step --> Connect to JetBrains via the /ide slash command
2. <!-- Second step --> Ask claude to make a change
3. <!-- And so on... --> When claude proposes changes, go into the right side of the diff (the "proposed" side) and make changes to the proposed text
4. Click "Apply"

Expected Behavior

<!-- What you expected to happen -->
I expect that changes to the text are kept when I click "Apply".

Actual Behavior

<!-- What actually happened -->
Any changes are undone, and what gets "applied" is the original text that claude proposed.

Additional Context

<!-- Add any other context about the problem here, such as screenshots, logs, etc. -->
This used to work, I was using this pretty heavily up until a few days ago.
