There were some GTK and WPE baselines that previously looked like correct results but should be treated as failures instead. Some of these baselines started failing between r258981 (last good) and r258993. Maybe because of bug208824. * fast/css-generated-content/initial-letter-pagination-raised-rl.html * Image diff with misaligned blocks. Related to bug169909? * fast/css-grid-layout/grid-align-baseline-vertical.html * Started failing two comparisons. Detailed diff in next comment. * fast/writing-mode/vertical-baseline-alignment.html * Both GTK and WPE vertical baselines are offset from the correct expected result. (Ideographs not centered, alphabetic text that should be centered is not centered in the middle block). For reference, check the mac expected result image.
