Bug Description

Actual Behavior

The DatePicker popup is not in the accessibility tree (does not repro on v8, related to v9 being modal). This is caused by a leftover aria-owns attribute that moves the popup from the end of the DOM to within the hidden tree. This was necessary when the datepicker was non-modal, but is breaking access now that it is modal.

The practical impact is that all screen readers and voice control are unable to access the dialog on the latest version of Chromium and Safari.

Expected Behavior

The DatePicker is accessible 😅
