The svg/custom/href-svg-namespace-static.svg reftest is failing on the GTK and WPE bots with an image-only failure. It was introduced in r234683. https://trac.webkit.org/changeset/234683/webkit The difference is minimal, 0.01%.

This was reported twice (by minutes). I'll close this one as duplicated and keep mine as I'm waiting for Said's feedback there, cause I'm not sure whether we need to add a new expectation for wkgtk or fix the general one. *** This bug has been marked as a duplicate of bug 188436 ***
