Issue with MSC streaming mode: long message fails the whole update
The streaming mode does not behave properly
when you execute the attached scenario step by step you see that the first message is displayed as expected:
However the second message makes it scroll up unexpectedly (this is the first problem)
then if you let the scenario run (adding messages), the messages move down (this is the second problem)
The drawing expands infinitely instead of keeping max 10 messages with a diagram of a fixed size.
Use the attached test script to reproduce. Place it in src/applications/msceditor/scripts (replace the existing one) and run the following:
$ msceditor -p 34622 &
$ ./stream.py
