QML registration does not work with custom qml static plugins

Hi, I really love the new way to register qml elements in Qt 5.15, but for my testing, I encontered an issue on iOS (and on iOS only) when creating a custom static plugin.

The error is the following:

QQmlApplicationEngine failed to load component
qrc:/main.qml:4:1: static plugin for module "MyModule.Uri" with name "MyModulePlugin" cannot be loaded: Cannot protect module MyModule.Uri 1 as it was never registered

I created the plugin as it recommended by the documentation using CONFIG+=qmltypes static and adding QML_IMPORT_NAME=MyModule.Uri

As I said, it perfeclty work with a shared plugin, as tested on macOS, windows and linux, but on iOS with static plugin it does not work.
