Regression I found out: Now the area is not clickable anymore, just the border, if the opacity is 0 no

My experience with Dynmap is limited. Is that something we can resolve on our end?

I've searched through dynmaps source as well, but I don't know either. I've created a separated issue as a feature request in dynmaps repo for that: webbukkit/dynmap#3637

@NotMyFault Found a workaround by setting the color to #FF000000 when the opacity is set to 0. The opacity is then set back to 1 and an 0-alpha channel is passed to the fill color. therefor the fill is still being added to the dom, but it's invisible.

Looks fine so far
