            When the very first tab (Tab 1) is fully visible
            On macOS:
            the left arrow button should NOT be visible.

            On other platforms:

            If the last tab (Tab 5) is fully visible
            On macOS:
            the right arrow button should NOT be visible.

            On other platforms:
            the right arrow button should be disabled.
