suwayomi-server:preview/WebUI opening anything in new browser tab stopped working after last update

[silferas]

Relevant info:
Suwayomi server: ghcr.io/suwayomi/suwayomi-server:preview
Server version: v2.1.2061 (docker)
WebUI version: r2937 (stable)
Browser: Brave 1.86.142 (Official Build) (64-bit) (rpm), Firefox 147.0.1 (flatpak)

Issue description: since last update, whenever I try opening anything inside of a new tab (tested most links inside the UI), all I get is blank window that never displays anything. Not after refresh (regular and ctrl+shift+r), or even when I copy/paste the link in new tab.

Attempts to resolve the issue: I tried downgrading back to stable, which broke a lot of things (dozens of SQL errors while attempting to connect to the library, some extensions that had been fixed on preview for months stopped working again etc.). I also tried switching browsers, which didn't help at all.

EDIT1: just downgraded to v2.1.2031-preview image and the issue was resolved, so it must be an issue with the newest build.

Have a similar/same issue with the docker preview.
Any page that starts with "http://localhost:4567/manga/" will show a black page when either refreshed, tab duplicated or when accessed directly via URL.... at that point, gotta go back to the main library page and manually navigate back to the manga page for it to load correctly.
Other server pages (library, updates, history, browse, downloads....) are working fine.
Tested the last few releases (on Edge and Chrome), the issue starts with version v2.1.2061, older versions are working fine.

Edit: The new v2.1.2078 fixed this issue.
