I've been following the docs for updating the styling of my map visualization using the below link.
https://developers.google.com/chart/interactive/docs/gallery/map#styling-maps
Despite the correct styling map options appearing in my map, I noticed the styling never changed.
I then noticed, that this is actually the case in the interactive example found on the page.
If you scroll to the option with three options (see below), clicking on each tab has no effect to the styling.
Is this a bug in a recent release?
