[css3-page] 'fit:hidden' unclear for images without intrinsic dimensions

The 'hidden' value of the 'fit' property in [1] should define its
behavior for images that have an intrinsic aspect ratio but do not
have intrinsic dimensions.  (We've made many clarifications to
CSS2.1 recently so that other things are well-defined for such
images.)

There really isn't anything good to do here:  there are reasonable
arguments to be made that such images should be handled according to
any of the three other values of the 'fit' property (although I
think the argument for 'slice' is somewhat weaker).  The
specification should pick one so that the behavior is defined.
