[Reg Qt6.4->6.5] The contentWidth of QML TableView is 0

After upgrading to Qt 6.5.1 (or Qt 6.5.0) from Qt 6.4.3, the QML TableView does not return contentWidth from delegate implicitWidth like it used to.
Attached sample application shows this well.

• With Qt 6.4.3 the TableView is visible and contentWidth is 200
• With Qt 6.5.1 the TableView is not seen as its contentWidth is 0

The sample application works also on Qt 6.2 and Qt 6.3, the error has appeared in Qt 6.5
