It has taken quite a while until it was understood why mistyped (un-renamed) methods are still found when using `snake_case`. It is a very old patch that searches hidden objects via the QMetaObject when normal attribute retrieval fails. This implementation is used all the time, but it is easily overlooked because most generated wrapper objects use this implementation from QObjectWrapper by inheritance, and is not found in the source code. Renaming these hidden methods the same way as the normal methods are renamed solves this problem. As a side effect, the solution to PYSIDE-1765 becomes more complete, too, since these hidden attributes were really missing. [ChangeLog][PySide6] The snake_case feature is now more complete since it renames hidden methods, too.
