Added transition to Quick View Extension.
Revert unneeded changes to jsTreeTheme
Fixed Quick View animation:
* Simplified positioning calculations so we don't need to keep constants in sync between the CSS and the positioning code
* Changed from using `offset()` to `css()` to set left and top (`offset()` wasn't working with the non-default transform point)
* Made the animation slightly faster (and tweaked inline editors to match)
* Made the animation grow from the top when the bubble pointer is attached at the top
Fix quick view unit test to not rely on offset() for popover
Add unprefixed versions of animation properties
