Incorrect strokeColor behaviour using property bindings and CurveRenderer

When using renderType Shape.CurveRenderer on a Shape, colour changes via property bindings don't appear to work as expected.

This issue does not exist when using Shape.SoftwareRenderer or Shape.GeometryRenderer.

test2.qml included, which provides a fairly minimal example of the issue and can be run in qml (or qml-qt6 on Fedora)

Having each ShapePath in the same Shape exhibits the same behaviour. Forcing a redraw seems to correct the colours briefly during the "flicker", but then it goes back to being weird. I've commented out the Behavior on strokeColor as it doesn't seem to matter if it's on or off, but I thought it was interesting that the sections incorrectly fade between the respective colours.
