includes
Whether the toolbar additionally reserves the side system bars — the navigation bar and display cutout when one is docked to the left or right edge, which is to say in landscape.
Only meaningful for a toolbar that spans the full window width: without it the trailing item (the overflow ⋮ button) renders under the 3-button navigation bar and never receives the tap. Set on the values that describe an edge-to-edge mounting; false where the caller has already accounted for the bars or is not edge-to-edge at all.
