There are probably larger changes that need to happen to ensure that the custom-layout and multicol play nicely together, but this removes a DCHECK crash for now. Bug: 823074 Change-Id: I98f4a34bd0c35e8cd3d23501ca64f38b96be9e7d Reviewed-on: https://chromium-review.googlesource.com/990780 Commit-Queue: Ian Kilpatrick <ikilpatrick@chromium.org> Reviewed-by: Morten Stenshorne <mstensho@chromium.org> Cr-Commit-Position: refs/heads/master@{#550148}
