When set with 'display: block !important;', from Tapir's testing:

IE9, Chrome: <input type=hidden> not displayed but getComputedStyle gives 'block'.
Firefox, Opera: <input type=hidden> not displayed but getComputedStyle gives 'none'.

Firefox and Opera's behavior seems saner and should be listed along with <noscript>

Comment 4 Ian 'Hixie' Hickson 2013-03-21 22:41:59 UTC 
None of them render anything, so I agree that it makes more sense to do it like <noscript>.
