Andrea Fercia e8fa2d66d0 Accessibility: Hide the Toolbar sub-menu CSS generated icons from assistive technologies.
CSS generated content is rendered for speech output. When it's not meant to be announced by assistive technologies, for example with font icons, special care should be used to hide it. At the moment, the only reliable way to do this is making use of a wrapper element and set `aria-hidden="true"` on it.

Fixes #37513.
