QFontDialog::getFont(...) always returns default font

When using QFontDialog::getFont(...), the inital font passed as the second parameter will always be returned, regardless of the font the user picked.

This affects my Macbook Pro (running Mac OSX 10.13.6). It affects 5.11.1 only, 5.11.0 and 5.10.0 work correctly.

Attached is an application that demonstrates this behavior.

Upon building running the application, there is a button to bring up a font picker to change the font of the textbox. Chose any font, and hit okay. The application will log to the console the initial font passed to the font picker, and will log the font returned by the picker.

In 5.11.1, regardless of the font picked, the initial and returned fonts will always be the same.
