Description
In the latest devtools, on the latest Firefox on the latest macOS, if I navigate to the "Components" and select a component for inspection, the inspection pane on the right side has no scrollbar. If I select and drag, I can scroll the window that way. I have no scroll wheel on my mouse, so I don't know if that would also scroll the pane. The left component selection pane also does not scroll, and I cannot scroll the left pane by selecting the text.

Research direction
Start by reproducing the missing-scrollbar behavior in the Components view on Firefox 139.04 and macOS 15.5, checking both the inspection pane and the component selection pane. Trace the UI entry points for those panes; done means both panes visibly support scrolling without relying on text selection or dragging.
