Question shouldHideMobileInput of password InputField

I have a question about the behavior when shouldHideMobileInput of InputField is set to true. The target is iOS. The attached test project has two InputField. The upper one is Password and the lower one is Standard. If I tap the upper one first, I can enter the password as expected. If you then tap the lower one, the earth symbol that normally appears does not appear on the keyboard, and you cannot enter Japanese, for example. It behaves as if once you touch the InputField of Password, part of its state is retained. This is not good. Is there any workaround?
