[bug] Opening links in another tab/window opens a broken login prompt instead of the link

[TangentFoxy]

Describe the bug
Opening a link in another tab triggers something that makes it look like you've logged out, but the page it loads doesn't work correctly either. For example, opening https://[domain]/book/1120 opens https://[domain]/login?next=%2Fbook%2F1120 instead, which looks like a normal login + redirect. The thing is, when you enter credentials and click login, it either returns an error (forgot which code sorry) or redirects to the domain only - ignoring the redirect.

To Reproduce
Steps to reproduce the behavior:

1. Right-click and open in new tab any link.

Configuration(please complete the following information):

• OS: Ubuntu 22.04.4 LTS
• Hardware: x64 server

Nothing has changed on my end except possibly a server reboot, but this isn't happening anymore.

That said, when I encountered this, it was on a different computer than I'm on now. (Vivaldi on macOS. Now I'm on Vivaldi on Windows.)
