The world-navigation-sidebar only closes, if you select something or reloads the page. It seems that this only happens with the "Galaxy Anvil" theme (the rest seems to work fine)
Open any world/change the world theme with/to the "Galaxy Anvil" theme open the world navigation sidebar Try to close it (without page reload)
Hello there! I am really sorry but we cannot reproduce that - is there any way for me to see where this is happening for you?
I made a short video showing the problem as I am experiencing it. (hope that it helps) https://youtu.be/sQmX54luODE The example is from Windows desktop. But the same problem is on android in both Firefox and Chrome. If you need something else, I will see what I can do. (I know that is a small bug, but it is very annoying when quickly look something up on the phone, and accidentally hitting it, and not being able to close it again.)
Thank you very VERY much for taking the time to make the video - I will have a look asap on the theme.
