Marker size animation disabled by axis range animation

[n-riesco]

Here's another codepen adapted from #1607 .

It shows that marker size animations work smoothly if the axis ranges don't change.
But if the axis ranges change, the marker size isn't animated, it transitions immediately.

I think this one will need to remain this way. The general case of transitioning data and layout at the same time resulted in a combination of interactions I was simply unable to tame. Marker sizes aren't that problematic, but there's no way to know or guarantee that it won't also be the x/y data changing.
