Test Result - Beta

Status: ✅ PASS
Environment: beta
OS: macOS Monterey
Browser: Chrome
Device: MBP
Emulated Device:NA

Test Artifact(s):

QA Steps

⬜ AC1: Instances of h3 are removed from Menu CSS and replaced with vector-menu-heading
This would be better for a developer to validate.

✅ AC2: h3 elements are replaced with label elements in modern vector
I validated that there are no h3 elements in any of the menus. H3 elements do appear in the body of the article as subsections.

✅ AC3: All menu styles remain the same in Vector and legacy Vector. Menus in this context include all "dropdown menus", "tab menus", and "portlet menus" (https://phabricator.wikimedia.org/F34972677)
I couldn't see any differences between prior screenshots and those of the current version. Here's what they both look like now.

@Edtadros Ac1 is a pass. The language section label probably could be updated to a label tag too but its not part of Vector menus, so its fine, AC2 is also a pass
