Based on when it started, this may be related to the custom pixel tolerance change in https://trac.webkit.org/changeset/287323/webkit

The test has <meta name="fuzzy" content="maxDifference=0-27;totalPixels=0-235"> so yeah

This patch modifies the imported WPT tests. Please ensure that any changes on the tests (not coming from a WPT import) are exported to WPT. Please see https://trac.webkit.org/wiki/WPTExportProcess
