Steps to reproduce:

1. Visit https://developers.google.com/chart/interactive/docs/gallery/piechart#3D
2. Click on one of the 3D pie chart segments.
3. The selected segment does not remain highlighted.

If you scroll up a bit and click a segment on a non-3D pie chart - the segment stays
highlighted/chosen after being clicked.

Nigel:

This is unspecified behavior that's existed in the API for years.

We are aware of this bug, and are tracking it internally, but don't have a resolution.
The bug is presently assigned to me, and we're working with our designers to find a
solution, but it hasn't really been high priority. I've tried a couple of solutions,
and no one likes any of them -- it turns out that when you have 2 rings (the hover
ring/glow and the selection ring, the chart looks bad). Unfortunately before resolution,
I've been pulled off to look at higher priority tasks.

I'll look to boost priority on this bug as it's now been flagged by external users.
