When the
touchmove
listener is registered withpassive: false
, scrolling up on Firefox Android only works every other attempt. When scrolling breaks, thetouchmove
callback is never invoked.The
passive
flag was originally set to false as part of a fix to prevent vertical scrolling while swiping: 3f31744. Settingpassive
to true doesn't seem to negatively affect that in both Firefox and Chrome, but fixes the scoll up behavior on Firefox.Fixes: #2053
