Deleting cookies results in endless loading indicator (sliding rectangle of death?) in Edge

[hodie]

I manually deleted the cookies for https://pacta.dev.rmi.siliconally.dev/en and now I can't load the page at all anymore. Trying to load it results in the loading animation playing forever (well, technically I only know that it plays for a few minutes).

Same as for #197 and #198 this only happens in Edge. In fact, deleting the cookies in Chrome doesn't do much of anything. I'm still signed in, the cookies just get recreated AFAICT.

Auth cookies are stored on an Azure domain (https://rmiauthdev.b2clogin.com/ IIRC), because we're using Azure's auth service (Azure AD B2C), so you have to clear the cookies on that domain to fully actually log out.

But yeah, auth stuff in particular needs a bit of work
