Full text of truncated messages cannot be shown
When gnome shell shows messages on screen or in the message tray, and the message is too long, it is truncated with "...". The user expects that pointing the mouse to the shortened message, clicking on it, etc., should reveal the full text. But this does not happen, the full text is never shown. Clicking the message makes it instantly disappear. I often have to guess what the messages tries to tell me. This should not happen. Here's a screenshot of a full screen message, but the same thing happens in the message tray, and also in the application overview (when application descriptions are too long).
