On a programatically generated node, if the style is set in javascript to, say S1 and then immediately changed to another (say S2), there is no transition performed (though there is a transition associated to the style). There are two workarounds: 
1. change the style inside a function called via setTimeout
2. Force a layout (for instance by querying a computed property such as clientWidth).

This is a dup.

Is this actually a bug?  I thought that this was pretty much expected based around the way transitions worked?
