Scrollbar.min.js update available

The native scrollbar won't hide on apple devices in firefox, and the browser displays both the native and the custom scrollbars. There's a new version of this plugin that addresses the issue by disabling the custom scrollbar on firefox. The update might not actually be advantageous, since the native scrollbar hides when inactive. So it will look like the list ends at the bottom of the viewport. And, trackpad scrolling is buggy, sometimes triggering the main window instead when scrolling over the sidebar.

Start by locating Scrollbar.min.js and checking how the custom scrollbar is initialized for the sidebar. Reproduce the issue in Firefox on an Apple device, compare the available plugin update, and verify whether native and custom scrollbars overlap and whether trackpad scrolling stays within the sidebar.
