[REG] Qt6.3.1 a MultiPointTouchArea inside another MultiPointTouchArea is reporting the wrong touch location

If a MultiPointTouchArea is inside another MultiPointTouchArea the touch points of the inner area are offset by its start coordinates insider the parent.

In the example included touching the top of the inner red Rectangle will give a y coordinate of 100 when the value should be 0.

This is a regression from 6.3.0 and 5.15.

This does not occur on macOS.
