Changes between Initial Version and Version 1 of Ticket #60680, comment 4

initial	v1
16	16	In my experience, the page has three columns as it loads: a Chapters list, the article content, and the "In this article" box. The columns remain that way when scrolling down, and the left and right side columns stay fixed in place.

18		I was able to achieve a different type of overlap in Chrome by scrolling down, disabling JavaScript without refreshing, and scrolling back up.
