You have to also add the mirror to the bridge, e.g.
        ovs-vsctl add bridge br0 mirrors a7fd3df2-d7bf-4a92-8133-22d9e7528338

You can create the mirror and add it to the bridge in one step:
        ovs-vsctl -- --id=@m create mirror name=mirror3 select_all=1 \
                  -- add bridge br0 mirrors @m
