Bug 1639448. When a visual viewport is set the page scroll amount for a scroll frame is incorrect. r?kats

No description provided.

We want to use a page scroll amount based on the visual viewport size.

The extra complications we have for not scrolling too far if there are fixed/sticky position things are quite hard to do properly with a visual viewport (I tried). I think there is far less user expectation of it working if a visual viewport is set. If we get complaints we can look into it.

This bug is currently impossible to see due to bug 1639450. However, I have a hacky fix for bug 1639450 locally which exposes this bug. Bug 1639450 is more involved so I'm going to land this fix since I have it, it should be able to shake out any possible regressions caused by it sooner.
