Detailed Description

CompatPropertySafePoint needs to be constructed before the setter of a QObjectCompatProperty runs. It prevents spurious binding dependencies caused by reads of properties inside the compat property setter. Moreover, it ensures that we don't destroy bindings when using operator=
