NGAP AllowedNSSAI IE not decoded correctly.

The AllowedNSSAI IE in NGAP message Initial Context Setup Request (3GPP TS 38413, vf00) doesn't seem to be decoded correctly.

The SD IE in S-NSSAI is optional. So, the optional bit field for presence has to be set/checked while encoding/decoding. However, wireshark seems to expect this IE to be mandatory. What version of the spec is wireshark compliant to?

Below I have the hex for the Initial Context Setup Message with only Allowed-NSSAI IE encoded.

The below hex is decoded (in this the bit field under S-NSSAI is not set) 000E000C000001000040050001010203

The below hex fails to decode (gives malformed packet error) 000E000C00000100004005001010203
