When input a too long message, the starting part is missing

If you input a message too long, it shows one line. But the starting part is missing, only the ending part remains.

I find that the problem only happens if a message is a full string without spaces. A message is displayed OK if it contains spaces. So I think messages are displayed without issues for most cases, so I am OK if this issue is closed without fix.
