Failed login doesn't preserve return url

[fdugdale112]

if a login fails for example if the password was wrong, the page seems to reload and all the url parameters are gone. I am using the default login page.

in my opinion these should be preserved so the user is redirected even if they got the password wrong on the first attempt

The initial URL with the parameters you're seeing is the request to the authorization endpoint which initiates the login process by redirecting to the login page after the parameters (like client id, scopes etc.) are verified.

Once the verification is done and we are on the login page the parameters are not needed anymore and thus they are not preserved when the login page is re-rendered.
