Steps to reproduce

1. Write a chat message and send it.
2. Use CTRL+UP to edit the chat message.
3. Now another participant should send a message while you are still editing/typing your own message.
4. In the edit screen, the cursor jumps to the first character. So instead of typing at the end of the message, you accidentially continue at the start of the message.

NOTE 1: It is more likely to occur when the other chat participant keeps sending messages. (Enough messages to trigger the text to scroll up.)

NOTE 2: It seems to only occur when the screen scrolls up (due to a new messages) and I am still typing on the keyboard. Without pressing any key it does not occur.

Expected behaviour

Messages from other participants should not interfere with me while typing a message.

Actual behaviour

The cursor is automatically reset to the first position of the message while typing.

@ShGKme Added to the description. And it's now 100% reproduceable for me, I've added two notes to the description.

I've recorded the issue... Notice how I start typing aaaa at the end of the message, but once the other participant's message is received, the cursor jumps to the start of my message and the aaaa's are added to the beginning of the message.
