Created attachment 468053 [details] Screenshot of the bug Steps to reproduce: 1) Open System Settings, Appearance, and set Show scroll bars to Always. This step is not necessary to reproduce the bug, but it makes the bug easier to see. 2) Open https://lapcatsoftware.com/articles/ in Safari 17. 3) Scroll down the page. 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.

I think you forgot to attach "before.png".

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