ah thanks, so I can also cross this off my backlog :)

Not a blocker, but maybe keep "More" as the visible label while preserving "More actions" as the accessible label for the trigger and submenu? This follows the existing pattern where compact text has a more descriptive aria-label, such as "Back" being labeled "Back to login form" in Login.vue:

server/core/src/views/Login.vue

Line 59 in 2bb9969

:aria-label="t('core', 'Back to login form')"

Thats more of an anti-pattern, visual label and accessible name should be the same and must not be too different.
See WCAG 2.5.3 https://www.w3.org/WAI/WCAG22/Understanding/label-in-name.html

must not be too different

"More" and "More actions" seem about as similar as can be, but it does seem best to avoid whenever possible - I.e. if there is not a compelling enough benefit to creating a discrepancy.

Needs adjustment of core/src/tests/components/AppMenu.spec.ts
