Overcome a limitation in kmlexport in 2018.
There are three functions below which might be copied into an existing
[[Module:Coordinates]] ([[d:Q7348344]])
or this module might be used stand-alone.
In templates it can be used then by
{{#invoke:Coordinates|kmlTitle|Some title for geohack}}
or respectively (as is)
{{#invoke:Coordinates/kml|kmlTitle|Some title for geohack}}
