Description

When proton sends pre-settled messages (the settled flag is set in the transfer), it follows up with an explicit disposition frame for the message.

I believe this disposition update is spurious and unneeded, though I haven't found a definitive statement one way or the other in the protocol specification.

[0x1efaaa0:1] -> FLOW @19 [0, 1024, 0, 1024, 1, 0, 8, null, false]
[0x1efaaa0:1] <- TRANSFER @20 [1, 0, b"\x00\x00\x00\x00\x00\x00\x00\x00", 0, true, false] (184)
[0x1efaaa0:1] <- TRANSFER @20 [1, 1, b"\x01\x00\x00\x00\x00\x00\x00\x00", 0, true, false] (184)
[0x1efaaa0:1] <- TRANSFER @20 [1, 2, b"\x02\x00\x00\x00\x00\x00\x00\x00", 0, true, false] (184)
[0x1efaaa0:1] <- DISPOSITION @21 [false, 0, 2, true, null]
