> Is there a max length defined somewhere for the message displayed in the status bar of the XML Editor?
No. There's a requested size for the whole XML dialog, but no maximum for the message itself.
Note that I'm still wondering why using a wrapped text doesn't give the same result with GTK-2 (to be precise, I'm a bit surprise it does work correctly with GTK-3 without additional code...).
Investigations in progress...
