sc2reader replay.messages and sc2reader.events.message.ChatEvent not getting all messages sent

It looks like SC2Reader for some reason isn't reading all in-game messages. I'm not sure if it's just this one replay or not as I don't really check through them. This one instance was brought to my attention, otherwise I wouldn't have noticed it.

When either using the chatevent or replay.messages a few messages are missed at a certain point in this specific replay. Messages from the user affected were processed earlier in the replay which is the weird part...
Heres the sc2reader output

Heres what I get from s2protocol

For some reason user 4's messages aren't getting processed at this particular time in the replay, but they were earlier...

Here's the replay if you want to take a look.

Reproduce the discrepancy with the attached not_all.zip, comparing sc2reader replay.messages and sc2reader.events.message.ChatEvent against the s2protocol output. Start by tracing how the replay's STr​iggerChatMessageEvent records are converted into chat messages, especially user 4's messages. Done means sc2reader reports the messages missing from the supplied comparison.
