What issue are you seeing?

In the Codex session page, the right-side draggable scrollbar/scroll thumb is partially blocked by the upper-right output panel. When the scroll thumb moves near that area, it becomes impossible to click or drag it with the mouse. I can only continue scrolling with the mouse wheel.

Actual behavior:

The scrollbar thumb appears to be covered or blocked by the upper-right output panel. Mouse clicks cannot select or drag the scrollbar thumb in that area, so scrolling by dragging is not possible. Only mouse-wheel scrolling works.

What steps can reproduce the bug?

Feedback ID: 019e4dc7-98c6-7a72-939e-ec9e4d154a5a
Open a Codex session page.
Use the right-side scrollbar to scroll through the session.
Move the scroll position until the scrollbar thumb reaches the area near the upper-right output panel.
Try to click or drag the scrollbar thumb.

What is the expected behavior?

The right-side scrollbar should remain clickable and draggable at all times. It should not be covered by the output panel or any overlaying UI element.

Additional information

This looks like a UI layering or hit-testing issue. The output panel may have a higher z-index or an overlapping pointer-event area that prevents the scrollbar from receiving mouse events.
