I wanted to bring up the following: I am using FacetWP for filtering on a client site. I have used this in Oxygen before and I don’t have this small issue with it.
When a facet has not been selected, FacetWP’s “reset” button should be hidden by default. They have the correct CSS loaded for that.
However, I guess to how Bricks’ applies it’s styles, it’s setting a display block 100% css rule on buttons to that reset element which is a “button”.
