Commented Unassigned: MessageBox does not use the default style of it's sub controls [20996]

Previously in v1.9 the formatting that the message box used was inherited from the controls inside of it.

In v2.1 the formatting is entirely different even though in both cases neither one has specified styling in my style file.

I have reviewed the styles and between the two versions the styling on the messagebox was changed to use the Toolkit.Prmitives.WindowControl.
