What's Wrong?

version 2.1.2

especially prevalent when I have more than one Claude code window open. Editing and scrolling unrelated code window should make claude code window scroll to crazzy places.

look at claude window on right, it is position near bottom.

do not touch claude windown, click in code edit window, and claude window scrolls to random location .

What Should Happen?

scolling the code window should have no affect on the claude windown
