Revert scrollbar
A recent update to Google's AI Studio (for Gemini) introduced a new custom scrollbar for the prompt history. This change replaced the familiar, full-page native browser scrollbar with a new one that is really buggy and constraint to specific prompts, and sometimes prompts don't even show up on the scrollbar, overall annoying as hell.
I found this new behavior less intuitive and preferred the classic scrolling method. This script reverts the change they've made. I'd recommend giving Google 'feedback', as well as using this script, because ideally they'd revert the actual website, so this userscript is useless. Otherwise, they'll have a false-sense that people actually like this change they've made.
The script is minimal, has no performance impact. I don't think you need to know JS to be able to read the code and see what it does.
