The position of a detached scrollbar is not set to 0 if the scrollbar is scrolled to its limit and then the size changes to >= 1.0 .

The attached example is from your documentation: https://doc-snapshots.qt.io/qt6-dev/qml-qtquick-controls2-scrollbar.html#non-attached-scroll-bars

I made the scrollbars always visible and added two buttons to change the size of the text.

Reproduce:

1. Start app, scrollbars work as expected
2. Scroll to the bottom right
3. Push "Small font"
4. The scrollbars size is wrong and the text item is moved outside the top left of the frame
5. On dragging the scrollbar fixes itself

Not sure if in your oppinion this is a bug, I think it should be.
