Created attachment 469147 [details] Minimal repro with and without slotted name VoiceOver does not read the contents of a label provided as the default contents of a child slot when the ARIA role is outside the shadow root. See the attached minimal reproduction. Note that if the `div` is removed from the shadow DOM, then the default label will be consumed as expected.
