* Demo app workaround/hack for initial miscalculation of hint placement

* Ensure ComboBox smart hint behaves according to MD spec

According to the "Behavior" section of the "Menus" page in the link below, the hint should float even when there is no selection, but the popup is open.

* Fix hint positioning issue when "readonly" element

The issue was present for all controls once they are in "readonly" state. Special handling of the case where the element is readonly, and the hint should follow the prefix/suffix needed to be added because of the "business rule" that prefix/suffix is always visible when the element is "readonly".

* Fixing so the hack is no longer needed

* Fix AutoSuggestBox as well
