1694002 - Make back/forward swiping harder to trigger accidentally

Status: RESOLVED FIXED

(Core :: Widget: Cocoa, task)

Description

[Markus Stange [:mstange]]

Our current back/forward swiping on macOS is very easy to trigger if the fingers are lifted with any amount of velocity. In other browsers, it seems like you need to "pull harder" before the swipe is executed.
I'm going to tweak our threshold values a little, to match the modern experience, and to prevent more accidental swipes.

This reduces the required swipe distance, but increases how much velocity is
needed to fling the page over the threshold.
On the touchpad, the result feels more similar to Safari now, in my testing.
With the magic mouse, it's still really easy to accidentally trigger a swipe
with a horizontal fling; it seems easier to accumulate a lot of velocity quickly
with the magic mouse.
