Geckoview scrollY and scrollX always 0.0 (zero) about geckoview

[dimaslanjaka]

fixed by adding scroll listener.

on activity

        // scroll listener - session is GeckoSession
        session.scrollDelegate = object : ScrollDelegate {
            override fun onScrollChanged(session: GeckoSession, scrollX: Int, scrollY: Int) {
                GeckoScrollHelper.scrollY = scrollY
                GeckoScrollHelper.scrollX = scrollX
                super.onScrollChanged(session, scrollX, scrollY)
            }
        }

on GeckoScrollHelper.kt

    companion object {
        var height = 0
        var scrollX = 0
        var scrollY = 0
    }

on method down

                    Timber.tag("scroll: start").d("$scrollY - $scrollX - $height")
                    // swipe down
                    MotionHelperkt.down(200f, {
                        // get scroll coord after swiped
                        Timber.tag("scroll: ends").d("$scrollY - $scrollX - $height")
                    })
