Opening a `ConfirmationModal` from a `ContextualMenu` does not move keyboard focus to the modal

When opening a `ConfirmationModal` from a `ContextualMenu`, the focus does not move keyboard focus to the modal. This issue may require more than one `ContextualMenu` elements to reproduce. `Shift+Tab`ing does eventually move the focus and trap it in the `ConfirmationModal`. The `tabIndex` to reach the `ConfirmationModal` is just before the first `ContextualMenu` component. Screencapture showing opening the modal, `Shift+Tab`ing as the focus moves behind the modal until eventually reaching and being trapped in the `ConfirmationModal`:
