What's Wrong?

Attempting to use voice input with split panels/tabs in the new Desktop version of the Claude Code app results in the voice transcription being input into all open window chat boxes as opposed to just the current selected project.

What Should Happen?

When I click the microphone on a single project, it should only put my transcription in that project.

Steps to Reproduce

1. Open more than one Code panel in the Claude Code app via the new split window funciton.
2. Press the microphone icon below the chat box in any of the open windows and speak.
3. The transcription will be autofilled into all chat windows, as opposed to just the chat window where the icon was pressed.
