The scroll bar in Safari won't disappear when I'm not scrolling

Hi! I'm using a 2019 (Intel) MacBook Air. I updated my OS to MacOS Sonoma 14.7.2. Before the update, I had Sonoma 14.7.x (I don't remember the exact version). Since the update, the scroll bar in Safari is not automatically disappearing when I'm not scrolling. I tried using "Automatically based on mouse or trackpad" and "When scrolling" options and restarted my system, but it didn't work. When I select one of these options, the scroll bar works as expected until I reload the page. After reloading, it again stays forever. The major inconvenience is that it is obstructing the content on some of the websites. It's also glitching while scrolling. I looked it up to see if anyone else was having this issue, but I didn't find anything. https://reddit.com/link/1hmcwnc/video/wgxpd57s839e1/player
