This would be equivalent to drop `org-hide-drawer' altogether, which we did for property drawers. You have to fold again every drawer after each visibility change. For the record, this is the initial bug `org-hide-drawer' was trying to solve. Back to square one. Also, we would have the same problem with blocks.
