What OS did you try this on? I encountered this issue on Windows, but
it seemed to be ok for me in Linux (I embedded GEdit successfully,
with keyboard focus working as expected):
https://bugreports.qt-project.org/browse/QTBUG-40320
createWindowContainer() was designed primarily for embedding
QQuickView in a QWidget, and it hasn't been fully polished/tested for
other use cases.
