Since updating to BlueMap 3.4 I noticed that markers and especially player markers are flickering back and forth between two worlds.

I don't know if this is somehow specific to my setup but to reproduce this, I can just load the webapp with the default map and then switch to any other map on the server. After a short while, normal markers, player markers or both start switching back and forth between the ones that are supposed to be on the different map and the ones on the default map. If I switch to yet another different map however, it doesn't switch between all three maps but again only between the default map and the one I'm currently viewing.

In the network tab in my devtools I can also see that every second player/marker request goes to the wrong url with the default map name. I'm sure it's possible to debug this further but I don't know enough about js debugging for that.

BlueMap version: 3.4 with a freshly regenerated webapp
Browser: Firefox

same thing but with normal markers (shapes to be precise but I guess it would apply to all plugin and custom defined markers)
But that was rarer. I managed to reproduce the player marker issue three times within like 5 tries while the other issue only happened once
