Bug, demande de fonctionnalité ou proposition:

Punaise

Quel est le comportement attendu?

Composant de menu de travail.

Quel est le comportement actuel?

Ouvrir un menu une fois le fera s'ouvrir et tous les boutons seront cliquables.
La console montre ceci:

Invalid keyframe value for property transform: matrix(0,01, 0, 0, 0,01, 0, 0)

polyfills.bundle.js:5856 ERROR DOMException: Failed to execute 'animate' on 'Element': Partial keyframes are not supported.
