WebEngineView contentsSize width not equal to width

We build our application with Qt/QML and 1 WebEngine. We have discovered that sometimes the contents size width does not follow the width of the WebEngineView item, when we are resizing the application window, as if the binding of the contentsSize with the item size is broken. The result is that the HTML in the WebEngine does not take the whole place, and displays scrollbar, in place of resizing with the window.

This happens in a random way, making it quite difficult to make a reproduction path. But maybe this problem rings a bell to you.

Thanks,

Bruno
