Ever since 1.20.5, the mod description has had 2 elements rendered on top of each other (e.g. the scrollbar was rendered twice). This is because it called the superclass, which rendered the scrollbar, and then rendered the scrollbar again from the subclass. The pull request of #864 was based on the redundant code and it works without it. This bug is previously mentioned in #712, which #844 fixes (by just removing the old code) (outdated now).

Removed in #866
