JSperformance:flarum/utils/ScrollListener.loop()

For some reason a tab in Chrome 59 with a Flarum.org discussion that I don't interact with uses approx 4% CPU on my MBP Pro 2014. Not a lot but this shouldn't be necessary and this is probably quite a drain on mobile devices. With the Chrome Inspector Performance pane it was quite trivial to pinpoint this to:

flarum/utils/ScrollListener.loop()

Apparently that method is called on each animation frame and for some reason this is triggered even for completely idle pages. Alas I'm not exactly a JS expert so I don't have a clue as to why this is happening or what can be done about this.
