That's... not true? dsa_port_switchdev_unsync_attrs() has:

	/* Port left the bridge, put in BR_STATE_DISABLED by the bridge layer,
	 * so allow it to be in BR_STATE_FORWARDING to be kept functional
	 */
	dsa_port_set_state_now(dp, BR_STATE_FORWARDING, true);

a dump_stack() could help explain what's going on in your system?
