See the screenshot "before.png". 4) Click the link to open an article. 5) Click the back button in the toolbar. Expected results: The scroller is displayed on the right side of the window. Actual results: The scroller is not displayed. However, the scroll area is still clickable and functional, even though the scroller is not displayed. See the screenshot "after.png". This bug occurs in Safari 17 and Safari Technology Preview 179 but not in Safari 16.

The scrollbar on your "before" screenshot is only half height. Does that always happen?
