Assigning [] to ShapePath.pathElements does not trigger a redraw

Consider the case one has a ShapePath with some Paths already added to its pathElements. Now I want to clear the ShapePath off all of its paths. Since we can not modify QML lists, we usually must assign a new javascript array to alter it.

Assigning the empty array "[]" to it clears its pathElements, as expected. But the ShapePath is not redrawn, causing the now deleted paths to still be displayed.

See the attached .qml file for an example.

Assigning null to ShapePath.pathElements is a workaround, but it prints this error message: QObject::connect: Cannot connect (nullptr)::changed() to QQuickShapePath::processPath()
