The document is loaded completely after
loadComponentFromURL() returned 
the model. But might be there are some asynchronous layout
routines.
On the other side such asynchronous layout must deal with
the situation 
that it will be disturbed from outside. And further you
loaded the 
document with HIDDEN=TRUE so there is no need for such
operations after 
loading.

For me it looks like a "simple .-)" bug. If it
can be reproduced by you 
with some special documents, please file an issue attaching
one or two 
test documents.

There is already such event. But it's not generated by the
component 
loader itself. It's generated by the document, which was
loaded and will 
be broadcasted by another singleton instance named 
com.sun.star.frame.GlobalEventBroadcaster (which implements
the 
interface css.document.XEventBroadcaster.

The callback css.document.XEventListener.notifyEvent()
contains a 
reference to the model. For loading (or creating empty)
documents exists 
different events.

OnNew  => for creating a new empty (visible) doc
OnLoad => for loading an existing doc (visible) from disc

OnCreate => for creating an empty (hidden) doc
OnLoadFinished => for loading an existing doc (hidden)
from disc
