This codepen shows an issue with axis range animations: a flicker is seen at the end of the animation.
I've tested Firefox 53 and Chromium 57. Only Firefox 53 is affected.

Still a problem as of FF58
Seems to be fixed in FF61

True, I don't see a flicker in the click animation anymore. But I see a flicker in the ctrl-click/cmd-click animation - in fact I see that in both FF and Chrome. Was that always there?
