dequelabs/axe-core v4.12.0

Release 4.12.0

on GitHub

In this release you'll find:

1. A new aria-tab-name rule that tests role="tab" elements have an accessible name
2. The landmark-complementary-is-top-level rule is deprecated, as ARIA no longer requires this
3. Preparations for Element Internal support (behind a feature flag)
4. Various other bug fixes for target-size, scrollable-region-focusable, and more

This release can see reveal new issues, as well as close out a few existing ones that might have come from false positives or the now deprecated rule.
