Symptom:
Group specific Query forwarded by the L3 interface is not sent out of the ASR903.

When the IGMP Leave packet is received, mrouter sends 2 GSQ messages to make sure that there are no more receivers interested in receiving the multicast traffic for the group before removing the interface from the forward list.. When a BDI is an mrouter, it sends GSQ messages, but these messages do not egress out of the ASR903. But IGMPSN GSQ's are egressing out of ASR903. IGMPSN is l2 feature whose GSQ's are egressed out.
