From 472398196d9109be16d13f3af4e8c423ce45d2e3 Mon Sep 17 00:00:00 2001 From: leviw Date: Mon, 14 Dec 2015 22:20:14 -0800 Subject: Implement Paint Containment Paint containment acts as a containing block for all objects, including fixed. It also clips them. It's also a formatting context and a stacking context. The approach in this patch differs from the spec in one very notable way: it does not mess with the computed style of the overflow property. This is a conscious decision I hope to work with Tab to address.
