When using VoiceOver on mac, most pages in a QWizard are not read out at all, and the window title is read twice.

The issues can be seen by using the trivialwizard example shipped with Qt itself. No modifications are needed. Before starting the wizard, turn on VoiceOver.

To reproduce:

• When the dialog first appears, the application name is read (correct), the window title followed by "dialog" (correct), but it repeats the window title (bug!) Attached is a screenshot of the text read out by VoiceOver
• On this page, it reads the whole text (correct), but:
• pressing the continue button, the wizard advances to the next page, but nothing from the new page is read out, not even the fact that the focus is still on the continue button.
• if you now switch away to another application, and then back to the wizard, the whole page is read out!
• when advancing to the last page, again the page content is not read out, only the fact that the focus is now on the done button

Added after testing on Windows:

• The dialog title is read out once, so correct
• The other issues are also present when using Narrator on Windows
