Works better it seems!
I believe we can do better if we mark the feature as experimental until Marble is working well for us. Still I think Marble has no competition from our perspective, just it's too much configurable and has rough edges when used as the component rather than app.
PS: I also observed crashes when:
- record is 72.3025;11.305;342 (zoom = 342)
- record is set to random type, string but not in the expected format
These issues may be fixable.
