Okay,
The test I did was with the stacks button (comes with stacks). The atribute with the BWD button doesn’t seem to get applied. It also doesn’t seem to work with sweet button, flat button, or Foundation 1 or 6 buttons.
The link attributes don’t seem to be coming across(@joeworkman @Elixir @isaiah?)
They do seem to come across fine with the stacks button, or with the link from within any styled text.
