Bug 1517976 - Test that resetting WindowUtils.isFirstPaint doesn't clobber APZ scroll position. r=botond We need to setup a case where the visual viewport is smaller than the layout viewport. Faking a pinch zoom through touch events is imprecise, whereas calling windowUtils.setResolutionAndScaleTo(value > 1) to simulate the equivalent effect of a pinch-zoom on the page led to the subsequent scroll attempt failing quite often even after calling waitForApzFlushedRepaints(). So instead, we set up a very wide layout viewport through the meta viewport tag, which on Desktop means additionally enabling the dom.meta-viewport.enabled pref.
