Being kicked because of too long message

[XakepSDK]

Sometimes, i'm being kicked because of chat message is too long.
I don't know, how to 100% reproduce this.
This 100% happens, when you try to execute some command.
This may happen after tabcomplete or sponge pagination system interaction.
Feels like some buffer overflowed because of previous messages.
Version: Chat UI 2.0.0

This is the same issue as #5. I thought I fixed that by splitting large messages into separate packets. So either the splitting is not working or a single line of text somehow encoded into 71248 bytes.
