Qt Quick Table View: can’t scroll to the bottom right of the content

On the new TableView QML component, it is not possible to reach the bottom right corner of the content. Instead, we are blocked before, as if we had already reached the bottom right corner.

It appears that the contentWidth and contentHeight properties are not computed properly: on my sample project, they both should be set to 25000 (500 cells that are 50 pixels wide) but they are set to about 24002 instead.
