No more possible to use a Loader for QML hot/live reloading since Qt 6.8.3

A solution for QML hot/live reloading consists in using a Loader and clearing the components cache of the QML engine, as described in the following links:

• https://www.youtube.com/watch?v=KSgl59mjBeY
• https://qml.guide/live-reloading-hot-reloading-qml/

But, it seems that this solution does not work anymore since Qt 6.8.3...

I have attached an example to illustrate this issue:

• a Rectangle is displayed within the entire Window (inside a Loader)
• a shortcut is used to activate the hot/live reloading of the Loader
• modifying the color of the Rectangle (in the Rectangle.qml file in the build directory) and activating the shortcut does not have any effect in Qt 6.8.3 and Qt 6.9.0
• the same example built with Qt 6.5.3, 6.6.3, 6.7.3 and 6.8.2 works as espected.
