I noticed there are some system notices in the admin panel, all of them are about network error when updating mirror repos. So I deleted one of them, but after the deletion, gogs redirected me to the wrong position.
Let's say I have control of the domain a.com, and I use a.com/b/ for gogs, and I've configured gogs options as followed.

[server]
DOMAIN = a.com
ROOT_URL = https://a.com/b/

But after deleting the system notices (the deletion request wen well with https://a.com/b/admin/notices/{ID}/delete), gogs keeps redirecting me to /admin/notices, while the right URL would be https://a.com/b/admin/notices.

I think gogs should respond with full URL instead of only the path of target URL.
