preferences: Broken language reordering on touchscreens
In the preferences dialog, there's a language chooser which allows to add, remove and reorder languages. However, when using a touchscreen, the reordering doesn't work - attempting to do it just scrolls the window.
Eventually, after attempting many times, it seems to sometimes switch to different kind of brokenness - where you can actually reorder the entries (although in a visually broken way), but you can't scroll the preferences window anymore.
