html - Div overflow scrolling when -ms-viewport is specified?

Question

Working on a page that is viewed in Windows Phone 8, and I noticed an odd behavior. When -ms-viewport is specified with a width or height, then it seems like users can no longer use the touch scrolling behaviors on an overflow:auto or -ms-touch-move:pan-y element.

Anyone encounter this behavior, or aware of any workarounds?

Answer 1

Setting the @-ms-viewport { width: auto } may not be acceptable for a number of applications that aspire to present a reactive UI on Windows Phone devices. A working alternative that allows you to set whatever viewport width you desire is to set the following CSS rule:

body, html { 
  -ms-overflow-style: none !important; 
}

I copied the original repro and fix it up with this rule at https://gist.github.com/tjanczuk/7419485.
