Marker overlapping with blocking

[mkgrgis]

In https://locator-tool.toolforge.org/#/map?category=Category:Muskau_Park&categoryDepth=7 there is a group of images with some equal non precise coordinates. It's normal situation, but on map only the last image is accessible.

No problems on https://wikimap.toolforge.org/?cat=Muskau_Park&subcats=true&subcatdepth=8
