Multi line text shadow in Firefox

I’ve been using Fabien Doiron’s Box-Shadow Method to create multi line padded text for a while. Just recently I had to find out that this isn’t working anymore in later versions of Firefox.

Turns out starting with Firefox 32 Mozilla has introduced text-decoration-break: split as default. Setting it to box-decoration-break: clone; does the trick.

Thanks to Chris Coyier for pointing this out.
