Messages notification covers empty message warning

[tomo3x3]

I have left opened the notification panel that says I have some unread messages and I clicked on Submit comment (comment was empty) button on some student's homework and the notification covered the warning text. Here you have a picture of that. I suggest you to put the notification into the background of that dark thing or to show the warning as next notification.

One small recommendation: Read your messages first! 😄 This is not a bug, this is a feature 😃
