JavaScript error in visitor map: Cannot read properties of undefined (reading 'name') #18756

Got below after clicking around in the visitor map (zoom out and then click on a country etc). Can't reproduce exact steps right now but wanted to create the issue anyway.

Wasn't able to reproduce that when clicking through the map for a while. Did that happen for a certain country only?

@sgiehl it happens when you click on a country like US, and then click again quickly while the data is still loading so that the regions are only shown for a very short time. I'll move it into backlog.
