Text stays half written in the message box

[mattnoir]

Not sure if I can describe it correctly, however when I write some longer messages, usually with multiple line breaks (shift+enter), and after sending the message I switch to another person to write. When I switch back to the first person, there is at least a portion of the original message still present, as if it was not sent. I am not sure, but I feel it's somehow related to the new line as only text after the new line (or several, usually two I believe) is missing. This is my best effort at making an example, please have mercy on me :D

Should be fixed in v2.56.1 (latest).
