Explanation

On the browser a minimized QDialog will always have a minimum of 24px padding.
On my iPad mini, the statusbar had a minimum padding for just the status bar, but the bottom had 0 padding. I believe that it should keep that minimum of 24px of padding, just like the browser.
No need to have 0px padding for dialogs on iPads.
