QLabel wordWrap = true caused weirdness in dialog sizing

Adding a QLabel to the layout of a resizaeable dialog, with wordWrap = true causes the dialog to be sizeable to any size, including sizes that do not display the controls.

I have attached a project with a main window that lets you launch two identical dialogs, with the exception of the wordWrap. One is sizeable but will not let you shrink it beyond a minimum size calculated by the size of the controls. The second, lets you size it down to any size.

Expected:
It is expected the second dialog would not size down to below the size allowing the display of all the controls.

I have attached a QtCreator project. It does the same thing on both Mac and Windows.
