This is a cumbersome, hackish workaround.  I shouldn't have to care about
whether an element might have its @hidden property set when I set an
element to inline-block, and I shouldn't need to hack up my CSS when I hide
an element.

The better solution would be for us to cascade the display type separately

Surely nothing prevents adding a CSS property, eg. "shown: no", which takes
precedence over display when set to "no" and does nothing when set to
"yes".  It's probably too late to change @hidden to use it, though maybe
not; it would probably break a roughly equal number of sites as the change
proposed here would.
