cctray.qml reloads the cctray.xml with 2 second timer. Drag the list view and wait for reload before releasing mouse. Four items become visible (although there are only two in the model) and focus starts behaving all funky, i.e. focus highlight is reset on each reload to a position outside the list rect, and the highlight item is animated from there to the current item.

Seems the list content rect is moved upwards with the height of the children, but the list items are drawn to correct positions (to be visible on screen).

No problems with only one project item in the xml.
