| 2 <!-- Inspired by https://github.com/othree/jquery.rtl-scroll-type which is used |
| 3 in various JS frameworks to determine what scroll "type" the engine has |
| 4 when it comes to RTL. When at the initial scroll position (i.e. all the way |
| 5 to the right), some engines sets scrollLeft to 0 and decrement to negative |
| 6 values when scrolling leftwards (Gecko). Others set it to 0 and increment |
| 7 the value when scrolling leftwards (IE / Edge). Others again set it to the |
| 8 width of the scrollable area and decrement it when scrolling leftwards |
| 9 (Blink / WebKit). There are further complications in the latter engine if |
| 10 there's a vertical scrollbar [1], and it's wider than the border box. All |
| 11 we need to worry about here though, is that the script is able to detect |
| 12 that we are "default". |

When moving past a left-hand scrollbar, don't jump way outside the content box. (Closed)
