MouseArea does not detect mouse pointer if it was already there on Mac OS X

On Mac OS X, when you load a component dynamically in QML and the mouse pointer is already placed where a MouseArea appears, the mouse pointer is not detected and the property containsMouse stays false. You need to click and/or move the mouse for it to work.
This does not happen on Windows.

Attached a simple example:

• Open the app
• Place the mouse on top of the rectangle => changes color.
• Don't move the mouse and close the app.
• Restart the app => Rectangle stays red until you move the mouse and/or click
