Most of the issues in the previous reply dialog related to the fact that: 1) The background content was taller than the viewport. 2) Background scrolling is possible with the dialog open. This change addresses this issue by hiding the bulk of change view content when any change view dialog is opened, and then re-displaying it when the dialog is closed, and letting the dialog take up the entire screen on smaller devices. Bug: Issue 7080, Issue 7070 Change-Id: I5834fc61e8daeee2972e8dca4fad9ac54bf9ebca
