Yeah, that'd work too.  ::after::after is just as unimplemented as
::after::outside, though, so shrug.

Hmm, do you think you can mock up some code for that?  I'm not sure
quite how that would work to achieve the same styling.  (You can see
how it is intended to look by taking the previous code I supplied,
replacing ::after with some div and ::after::outside with a wrapper
div, and replacing the calc() expression with a value like "40px".)
