Add tests for !LayoutContainer's new API: !LayoutContainer.design and children using region and layoutPriority.  Note that for backwards compatibility,  "design" shouldn't affect children that set layoutAlign instead of region.  This is basically "accidentally" working due to the way _getOrderedChildren() happens to be written.  Refs #16770 !strict. 

Also convert uses of deprecated layoutAlign in calls to utils.layoutChildren() to region, refs #16585 !strict.

Add CSS classes for Editor ComboBox's, fixes #16983 !strict.
On touchend on the placeholder, focus immediately, rather than delayed by a this.defer(), so that the keyboard pops up.  Fixes #11578 , refs #16725 !strict.
Do not adjust the height of the viewport on iOS if the focusedNode is read only.   Because readonly nodes don't cause the keyboard to popup.  Thanks Sebastien Brunot (IBM CCLA).  Refs #16730 !strict.
Account for when viewport ends before the bottom of the screen, and thus keyboard is not obscuring as much of the viewport as we thought it was.   Fixes #16989, refs #16730 !strict.
