Hey, me again.
Very happy with what I get using the popup module particle.
Just one thing : my popup is calling a custom HTML particle which includes a link (looking like a button).
Well, I'm noticing this link is not active by default in Firefox.
I mean I have to click once anywhere on the page (even on the overlay) before it gets active (for instance the hover state is not triggered). So any action (make the popup disappear or click on the link) requires 2 clicks rather than one.
No problem on Safari tho.
Any idea where it's coming from? z-index or something?
