Yes, I've tried my own key and it doesn't work as well.
I've tried a simplified version with just "get started" maps. I've also tried the latest chromium 112. The problem preserves. There is no info logged, the maps simply don't load visually or emit js events. I've also tried to put it into flxexbox. I don't know how to further troubleshoot it, it's related to chrome and google maps more than to jsreport.
I found this related bug in chromium.

Perhaps it gets propagated to a new release, but I am a bit skeptical.
Chrome fixes come very rarely.
