swiping back gesture (windows Surface 4 Pro) w/ 3 fingers not working properly

[theobromine]

Hello
I really dig this browser, but the only issue I have is that the built-in swiping gesture for "going back" (using the trackpad) in the history to the previous site doesn't work properly. When I swipe left with 3 fingers, it goes back 2 pages at once, not 1. The forward swipe works normally one page at a swipe.
Is there a fix for that? can someone confirm this?
Thx!
