Reverts changes 69df963, 0c7c5d59, 6cbef19 and others. These changes
don't revert cleanly because of several refactorings layered on top
of the original changes.
The main objective of these change is to get rid of mUseLayoutForBrowseable
and associated codepaths as we treat choosing between browseables the
same as other choices.
