The "change style" example in the Docs generates the following warning: Unable to perform style diff: Unimplemented: setSprite

[ggrocca]

This is just a warning, no broken functionality here. My wild guesses are that there's something wrong in the Docs example, or there's a spurious warning that needs to be fixed (third possibility: this warning is due to an open issue, but I see that issues #2058 and #2059 are closed). I'm totally new to mapbox though (just started to playing with APIs a few days ago, so apologies in advance if I'm missing something obvious).

Full warning:

Expected Behavior

No warning.

Actual Behavior

There's a warning.

While the warning can be safely ignored, we're still interested in speeding up setStyle for cases like this, so let's reopen #2058.
