Unless you did so already, I'd connect a dummy-object to all the signals a
model can emit to verify
which are being emitted while you add your rows.

But you're adding rows as children under the one that is already expanded,
not as siblings to it?

I'd say it should be possible, but I don't know the QTreeView code off-hand
to be 100% sure. I'd file a bugreport with the Qt-Project if a
stripped-down example of what you do causes the same problem.
