[Bug] Firefox: Fog is not working properly for players
Masks (Obscured and Hidden) are not working properly for players who use Firefox. They just see the whole map. Exception: If they scroll until all tokens are barely outside the visible field it's working propery, the map gets darkened and you can only see the lighting area around the token. (GM's view is not affected.)
I played around a bit and found interesting behaviour: Everything works as intended if the player adds a token to the map. But the mask/fog disappears the moment the host adds a token.
Ok, I kind of solved it. When I delete the node use class="scene-grid" href="#scene-grid" the mask works perfectly. I have no idea what this will break, but for me it would be the fix.
Thanks for reporting this, I should be able to test and debug this soon.
