The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/5728bdc52ff12d4f70a96b79a93508c90bca2b94

commit 5728bdc52ff12d4f70a96b79a93508c90bca2b94
Author: Robert Hogan <robhogan@gmail.com>
Date: Wed Aug 23 00:18:02 2017

Check if page height is known when painting table footers

The testcase no longer fails due to unrelated changes, so this is a
preventive measure - it was an oversight not to add it when landing the
original CL.
