I've found myself facing the same issue, and found no answer online. Finally I've found out that some optimizations were added to Fragment Transactions in Revision 25.1.1 of the Support Library. (see https://developer.android.com/topic/libraries/support-library/revisions.html#25-1-1). Disabling those for your transaction will make it work as expected:

FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.setAllowOptimization(false);
transaction.detach(fragment).attach(fragment).commitAllowingStateLoss();

Update

setAllowOptimization is deprecated. Use setReorderingAllowed instead.
