AntiforgeryValidationException when logging out of Blazor Web app with global interactive WebAssembly rendering enabled

[danroth27]

Repro steps:

• Create a new Blazor Web App with global interactive WebAssembly rendering enabled and individual user accounts for authentication
• Run the app, register a new user, and log in.
• Log out

Expected result: Log out is successful
Actual result:

Microsoft.AspNetCore.Http.BadHttpRequestException: Invalid anti-forgery token found when reading parameter "string returnUrl" from the request body as form.
---> Microsoft.AspNetCore.Antiforgery.AntiforgeryValidationException: The required antiforgery request token was not provided in either form field "__RequestVerificationToken" or header value "RequestVerificationToken".
