[BUG] VS-Code: Execution stops when moving the Claude Code tab around

What's Wrong?

When you move one of the Claude Code tabs in VS-Code around (either in a new VS-Code Window or between them), execution stops when Claude is currently working on something.
The only way to get Claude to finish off is a message telling them to continue. This happened to me several times now and considering I sometimes have multiple Claude Code sessions going at once, this is a bit annoying.

What Should Happen?

Claude doesn't stop working on whatever it's working on when you move the tab of it in another Claude Code window or use the VS-Code tools to move it into a new one.
