The WPT test css/css-grid/grid-model/grid-box-sizing-001.html fails on WebKit browsers: Run the test here: https://wpt.live/css/css-grid/grid-model/grid-box-sizing-001.html See results for other browsers: https://wpt.fyi/results/css/css-grid/grid-items/grid-item-percentage-sizes-001.html?label=master&label=experimental&product=chrome&product=edge&product=firefox&product=safari&product=webkitgtk&aligned This test was added by https://bugs.chromium.org/p/chromium/issues/detail?id=772512 so its likely a similar issue to what was reported there for Chromium also happens on WebKit.

The changes introduced on that bug were already ported in bug #178783 (r225101). So there might be something else.
