Support Front-channel logout URL

What feature do you want to see added?

Hello. I was trying to setup single sign-out in Entra (logout from Microsoft should also terminate session in Jenkins) and configured "/logout" as "Front-channel logout URL" for my Entra application. When I tried to test that I saw that the browser was making a request to the logout URL but without any cookies and the browser probably ignored "set-cookie" header too because of third-party cookie policy or something. That results in a state where a user is logged out from Microsoft but still logged in in Jenkins. Is it feasible to add a logout URL that won't be relying on cookies, but will instead use "sid" request parameter?

I couldn't find any discussions about this and it seems like a basic feature so sorry if it is already implemented and I'm just doing something wrong.
