Password entry impossible in Storekit with large dynamic text sizes

I am using Storekit 2 and SwiftUI in my App and am testing it with 'Larger Accessibility Sizes' on and the largest text size selected.

When I call the .purchase method of a Product object I get the Purchase confirmation screen followed by the prompt to enter my password as expected.

The problem is that with higher text sizes and small device screens, the password box is not visible, not can it be scrolled up:

There does not seem to be a way of accessing the password screen to control its layout. I have tried unsuccessfully wrapping the request in a view with the modifier: dynamicTypeSize(...DynamicTypeSize.accessibility1).

Has anyone else seen this behaviour? Is it a bug that I should report?
