Multiple Tab Login AD B2C Get BadRequest

I have been working with ad b2c, sucesfully configured an app and created a login flow, I have already created a login connection using MSAL library with REACTJS, and is working good. However, if I open in 2 different tabs the url login, while in the last will be sucessfuly logged, when attempt login in the first one, this will give me a bad request error.

Also, I have tried running this from user flow on azure portal and using "authorize URL", but I am getting the same error. I have been working on this for days and did not find a solution. I will be very glad to find an answer here.

If it is need more information to workaround with this situation just let me know.

@AlejandroAlvarez-0114 This is by design. As of now B2C doesn't allow multiple sign-ins within same browser session.
