Change subject: Make ve.ce.Surface.getSelectionRect() work on Opera
......................................................................
Make ve.ce.Surface.getSelectionRect() work on Opera
.getClientRects() on a collapsed native range returns an empty
collection on Opera, causing an exception to be thrown by rangy.
Handle collapsed ranges separately, by using .surroundContents() to
insert an empty <span> into the DOM, then read the span's offset.
Bug: 47772
