Hello! We are upgrading our axe version from 4.0.0 to 4.4.1 (yes we are a bit behind).
Previously axe reported summary[role='button'] without an accessible name as a violation. However, since the upgrade, it is no longer reported. I notice there were some changes with some of the logic in button-name being moved into a new aria-command-name.
I believe any element with [role='button'] without an accessible name should be reported.
