When calling QQmlEngine::retranslate() it will cause the background of a highlighted MenuItem to be smaller than the Menu width.

Before calling retranslate() it will be correct as the highlight will go all the way across of the menu width, but after retranslate is called it will be just the size of the text. In the example, move the mouse over a menu item and then wait a few seconds before it will redraw and be too short.

This is only in the Imagine style as it is fine in the other styles.
