Once the new grid-auto-flow syntax is ready (bug #134057) we should implement proper support for stack mode in auto-placement algorithm.
After some discussion in the CSS WG, in the last update of the spec "stack" mode has been dropped: http://dev.w3.org/csswg/css-grid/#propdef-grid-auto-flow We need to update the syntax again to remove "stack" option and also remove the pending FIXMEs from the source code.
