[REG 6.4?->6.5.0b3] Material style in iOS not respected by all Controls and makes Styling inconsistent.

I have an app, that runs in Material style even on iOS (set via qtquickcontrols2.conf) and starting with 6.5 there are inconsistencies in the styling:

At least these 3 controls:

Switch, TextField and Button { flat: true; checkable: true }

are not drawn in Material style, but in Native (iOS) style, which look totally out of place. You can easily check that by running the gallery_controls2 example on IOS (simulator) and force the style to Material.
