- 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:
