PRP Dissector and FCS

edit

I got an ethernet capture made with a fluke network analyser so it does contain frame checksum octets, unlike normally when captured with winpcap. Problem is that PRP-1 dissector does not seen to find the RCT trailer when the FCS is present. I have wireshark 2.4.2 on Win7, with PRP dissector enabled in the Enabled Protocols menu.

Is this by design or is it a bug? Should I file a bug for it? I was not able to add an attachment here, I tried to add a small pcap file with just single message as an example.
