If it is expected behavior, then there is some bug or flaw in browsers, or my understand of how multi-select works:
1) IE and Firefox work differently than Chrome. In IE and Firefox, you can move items around (as expected), and scale items (as expected).
2) In Chrome, you can ONLY multi-select. you cannot move or scale any individual item or group of items. The video (probably poorly) shows me trying to select a single item and move or scale it. It doesn't seem possible.
Is there some mode that Chrome is setting that will not allow it to go out of tablet/touch mode (that is not set in IE or Firefox)?
