There are two ways to do bridge-domains and vlan trunks on MX.  The
old way uses separate units for each VLAN.  The new way uses a single
unit 0 with all vlans in a family bridge.  Try doing it the "old" way,
pre-"family bridge interface-mode trunk".  I don't think you can mix
the two ways.

interfaces
    xe-2/0/2 {
        flexible-vlan-tagging;
	encapsulation flexible-ethernet-services;
	unit 100 {
	    vlan-id 100;
	    family inet {
	        unnumbered-address lo0.1;
	    }
	}
        unit 200 {
            encapsulation vlan-bridge;
	    vlan-id 200;
        }
        unit 300 {
            encapsulation vlan-bridge;
	    vlan-id 300;
        }
    }
}
bridge-domains {
    vlan-200 {
        domain-type bridge;
        vlan-id 200;
        routing-interface irb.2;
	interface xe-2/0/2.200;
    }
    vlan-300 {
        domain-type bridge;
        vlan-id 300;
	interface xe-2/0/2.300;
    }
}
