Inconsistent behavior when AllowNewAccounts = false in the AuthProvider.Email UI between the old and new library versions

There is inconsistent behavior when AllowNewAccounts = false in the AuthProvider.Email UI between the old and new library versions.

While updating the library from version 8.x.x to 10.0.0-beta03, I encountered the following problem:

It seems that the new version of the library behaves quite differently regarding the "setAllowNewAccounts" option in AuthProvider.Email.

When using the old version, the sign-up button disappears when AllowNewAccounts is set to false.

When AllowNewAccounts is set to false using the new version of the library, the sign-up button remains visible but is always disabled. An ugly pop-up message appears as soon as the sign-in UI is displayed: "This button is currently disabled because new accounts are not allowed."

This message is not relevant to my app, which does not allow sign-up at all. It is especially problematic compared to the cleaner UI obtained with version 8.x.x of the library.

@nerocristallo thanks for raising this — we'll check internally with the team on whether this should be considered a regression from 8.x, and follow up here once we have an answer.
