I can't seem to reproduce locally and can't follow your steps since IIS doesn't run on Linux, however I have verified that the original issue is still fixed, so if you've tested it maybe we should just merge?

Let's do that - I have verified it locally with IIS. |

Prerequisites
Resolves: #18509
Description
It looks as if #18206 introduced an issue in this situation, where you have a user authenticated via IIS basic authentication before attempting to sign-in to the backoffice.
I haven't been able to reproduce it using the public access feature on Umbraco Cloud.
I've been able to reproduce locally: #18509 (comment) - so these are the test steps.
When I try this process again with the code from this PR in place, I no longer see the issue.
