STR: 1. Load this testcase: ``` data:text/html,<!DOCTYPE html><div style="display:flex; align-items:baseline;border:1px solid black"><div>abc</div><fieldset><legend>Legend</legend>F1<br>F2 ``` EXPECTED RESULTS: "abc" should be baseline-aligned with "F1" (i.e. the fieldset's body) ACTUAL RESULTS: "abc" is basleine-aligned with the fieldset's legend instead. Chrome gives EXPECTED RESULTS. Firefox and Epiphany (Powered by WebKitGTK 2.38.5) give ACTUAL RESULTS. This is the reason we fail several interop-2023-relevant WPT tests: https://wpt.fyi/results/css/css-flexbox/fieldset-baseline-alignment.html https://wpt.fyi/results/css/css-flexbox/alignment/flex-align-baseline-fieldset-001.html https://wpt.fyi/results/css/css-flexbox/alignment/flex-align-baseline-fieldset-002.html https://wpt.fyi/results/css/css-flexbox/alignment/flex-align-baseline-fieldset-003.html
