Chrome for Android 4.4 - node-scroll-info errors

[clarle]

ScrollInfo on Chrome (31.0.1650.59) / Linux
   in ScrollInfo
     body: getScrollInfo() should return current scroll information: 
     atBottom should be true after scrolling to bottom
       Expected: true (boolean)
       Actual: false (boolean)

     body: scrollToBottom event should fire after scrolling to the bottom: 
    Timeout: wait() called but resume() never called.

     body: scrollToRight event should fire after scrolling to the extreme right: 
    Timeout: wait() called but resume() never called.

Tested on a Nexus 7 (2012, 1st generation) with Android 4.4.2, errors are continuously reproducible.

Setting user-scalable=no in the test page's viewport meta tag resolves this, but that's obviously just squelching the problem since ScrollInfo needs to work on user-scalable pages as well.

Chrome for Android seems to choose a weird initial scale by default, and then doesn't report the correct pixel values when getting the height of the document. Which really sucks. :(

I'll have to investigate whether there's a way to work around this.

@rgrove I'm guessing that this and #1484 have the same underlying issue then, with the weird scaling?

Seems likely, although I don't know anything about ScrollView.

Note for the future. If a bug's a release blocker let's note it in the description so everyone's aware.
