Metadata editor is small after many mistakes

[matthias-ronge]

After many errors have occurred …

… the metadata editor is small and lots of white space remains down. It never changes after that:

Goal: The metadata editor should use the available screen space again after error messages have gone.

The + icon for adding Metadata dissapears

Yes, I noticed that, too.

A possible solution might be:
Add a click listener to body or something similar and check for every event if the real target is the close button of the messages. (It is not possible to add a listener directly to the close button without changing the primefaces component.)
If the close button was clicked, execute the JS resize method.
