Roles are not converted to Claims on Login

### Describe the bug
Currently, I have Remote Auth setup using SystemWebAdapters. Going from .net 4.7.2 MVC using Simple Membership with default setup to .NET 8.

.NET 8

Forms:

Everything is working with Authorization, it logs me in and logs me out and I can tell when a user is logged in just fine. However on the Framework side I have like 85 roles and on the .NET side I have only 1 claim for my username.


After a discussion in this thread: https://github.com/dotnet/systemweb-adapters/issues/331 I tested manually casing my user to a claims principal and that seems to work fine, as you can see I have all of my roles:


So what I want to know is should systemwebadapters be converting my roles automatically or do I need to do some extra configuration for that to work. From what I was reading, it seem like this should work automatically for all of the old out of the box authentications in MVC so I'm not sure why this one isn't working.
