Lets investigate getting the specification fixed before we break with Firefox, IE, and WebKit’s own historical behavior in the name of matching the specification wording.

I tried the testcases on ie 10 and it is following the spec. That means that we have 2 shipping implementations.
It really makes sense to disallow this edge case. If the start and end point of a gradient coincide, there is no 'direction' so it's impossible to tell how the gradient is supposed to draw. 
My vote is to fix this in the webkit and mozilla implementations.
