To address #25571 for the Properties panel, can we use StyledFlickable in InspectorSectionDelegate.qml to obtain the height of the navigated item and ContentY..... or would there be a better solution? I'm open to suggestions for this.

@shubham-shinde-442 I don't understand exactly what you mean, but can https://doc.qt.io/qt-6/qml-qtquick-item.html#mapToItem-method help, to retrieve the bounding box of an item in the coordinates of any other item (for example the contentItem of the StyledListView that contains all the inspector sections)?

Thanks for your contribution @shubham-shinde-442 - just a couple of feedback points.

It's a shame we can't use positionViewAtindex in our version of TreeView - this would make life a lot easier!
