Spinbox Range in QtDesginer

The Designer tool of QtCreator, and I assume the standalone Ui-Editor as well, does not allow all inputs that a QSpinBox can have.

It seems like there's an Input-Validator/Mask that prevents users from inputing any number with more than 9 digits.

But the QSpinBox allows a range between std::numeric_limits<int32_t>::min() and std::numeric_limits<int32_t>::max()

-> -2147483648 and 2147483647

10 digits
