I'm noticing inconsistant behavior while scrolling on pull requests sometimes. This occurs sometimes when I'm looking at a diff of a pull request, with my mouse over the code - some sort of javascript triggers on scroll and adjusts the scroll location, sending me jumping around the page, typically in the opposite direction than I'm scrolling in. This either results in me scrolling extremely slowly, as I make very little progress; me not scrolling at all as the jumping cancels out my scroll, or me jumping all over the page before managing to reach my intended destination. I'm using google chrome on a 2012 MBP.
