As I explained in my previous email, this reading of the spec language
(where the stops are ignored) was never intended, and I've reworded
the relevant section of the spec to attempt to make it clearer that
this is talking about the locations on the gradient line (color-stops
are placed *at* locations, they are not locations themselves).

Does this address your concerns?
