This PR brought two problems:
1. When moving the map, a white flash occurs and all objects on the map are
redrawn:
https://github.com/user-attachments/assets/3c87c769-174c-4513-a5be-115eb9517bb8
2. Rendering slowed down. What used to occupy ~400ms now occupies ~1.3s. Hiding
a data layer was previously performed on ~100ms, now ~1.5s (!)
Both problems arise due to the fact that before that the redrawing of the map
was performed only once, after the completion of the removal/adding of objects
to the SVG-element of the map.
I can agree that the first appearance of the data layer looks beautiful. But
the work with the map worsened.
