What's Wrong?

When viewing status or config screens (e.g., /status, /config) in VS Code's integrated terminal, scrolling behavior is broken depending on terminal height.

Actual behavior:

• When terminal height is large enough: scrolling works
• When terminal height is below a certain threshold: scrolling doesn't work and the screen "jitters/flickers" repeatedly

What Should Happen?

Normal scrolling should work
