[REG: 5.8->5.9]: Controls 2 BusyIndicator animation does not update if it is inside QQuickWidget

When having a busy indicator inside a QQuickWidget, it's animation does not update. When resizing or moving the window to another monitor, the busy indicator animation is updated once. If constantly resizing, the animation works as expected.

Controls 1 BusyIndicator works properly, and this is a regression from 5.8 to 5.9.

Steps to reproduce:

• Run attached sample
• EXPECTED: BusyIndicator is properly animating
• ACTUAL: BusyIndicator animation is stopped
