What's Wrong?

When using claude in PyCharm community edition, I can't scroll up through the conversation using my mouse scroll wheel or using the ctrl+up/down buttons. Using the pgup or pgdown works correctly.
Using PyCharm Professional or PHP storm everything works fine.

What Should Happen?

Should be able to scroll up using the mouse wheel.
