I'm trying to delete a QQMLEngine without having warning in the console from qml/bindings.

Before deleting, i do

// Stop bindings to delete faster
m_engine->setInterrupted(true);
// Disable warning to the console/log file
 m_engine->setOutputWarningsToStandardError(false);
// Delete
m_engine->deleteLater();

It work almost as intended but because of "setInterrupted(true)" all binding return undefined
and for some bindings on Text, i still get warnings in the console

QFont::setPointSizeF: Point size <= 0 (0.000000), must be greater than 0
