Revert v1.13.1's changes temporarily

[tony]

The reason why is I have upcoming changes and refactorings (like #805) that are noops, and we should at least stay with the earlier broken behavior (the broken behavior we know) while we investigate a better way to do v1.13.1. Me and @nvasilas will release an improved solution

Revert "Fix layout related issues #737, #667, #704"

This reverts commit fb9a8af.
