QTreeWidget updates twice when using mouse to select items

The QTreeWidget updates twice when using mouse to select items.

On a fast machine this is difficult to notice, but on slower machines it is possible to notice that the selection is first updated in one column, then updated in the remaining columns.

When clicking inside the QTreeWidget to select a new row the column item under the mouse gets seleted first, then quickly after the rest of the items on the row are selected. This only occurs when clicking the elements.

When using the arrow keys to move the selection up and down the items in the QTreeWidget the problem is not shown. It is only shown when selecting an item in the QTreeWidget by pressing the mouse.
