Created attachment 469163 [details]
Button with component label in and out of shadow

An accessible name slotted into a child component of a simple button (or any other ARIA role) fails to be read by VoiceOver.  This only occurs when the role is also in a shadow root, i.e. the same code works in the light DOM.  Please see attached very minimal reproduction.

This is a major regression in Safari 17 as it can break labels for even very simple components.
