### Bug description

Forgive me I have near zero experience with google maps.
If I copy this code to a .html page on my linux server should a map open (with the existing Google maps API key)?

https://github.com/googlemaps/js-samples/blob/bdfbfc1db0d0680e361132bc54bdf580b3bdee34/dist/samples/map-simple/docs/index.html

With existing key or my own key that is authorised on my IP I get a blank white page. I can see alll the code in source.
Thanks Colin K

### Steps to reproduce

copy the code to an HTML page, upload to a server.

If necessary swap the Google API key for your own and ensure your key is authorised for your site or your IP

### Console log output

```sh
none - other than style.css error
```
