Maybe we need an extra flag to determine if the native props have already been updated and reduce _applySecureWithoutAutofillTraits calls since there are cases like reloadInputViews() that might be called multiple times while typing.
For instance, the old fix made sure to check whether secureTextEntry was already enabled or not before proceeding.
const delta = replacementString.length - range.length;
if (delta > 0) {
if (textField.text.length + delta > this.maxLength) {

Is cast to any necessary here? I understand these props are available in UITextField.

Some properties are sdk level scoped so we can probably rather use SDK_VERSION scope on some.
