UWP applications do not detect a mouse button released outside the application window

Tried to run the Stocqt example as a UWP application on Windows 10. While dragging the list view, if I click and hold the mouse button over a cell, then move the mouse pointer and release the button outside of the window, the button release is not detected and the view stays in a dragging operation even with no button pressed. But it is not something specific to this example. It seems to happen with all widgets in all examples.
