Introduce fixes and more rigorous tests for 'Show on a map' feature (go-gitea#26803) (go-gitea#27365)

Backport go-gitea#26803 by @n0toose

This change introduces some fixes for my original PR
(go-gitea#26214) and introduces some
additional tests so that such a regression does not happen again in the
future.
