Restores YouTube Studio's Material 2 UI before the Jun 2024 overhaul
This userscript sets an interval that detects any YT Studio element with the "modern" attribute, and removes said attribute for any "modern"-attributed element it detects (except some of the comments ones, bc I tried and the comments page got half-broken with some elements missing the attribute), ultimately restoring the pre-Jun 2024 YT Studio UI. This also adds additional css that fixes up a few elements that may look broken style-wise
Additionally, you can also use this alongside the "YouTube Studio Old Icons" userstyle (not owned by me, credit to ytuserstyles) for a more complete experience with the old icons from pre-Nov 2022
Changelog can be found on the history tab
