The server is not requesting these images through an extension; thus, it is not a problem to send them directly to the server since there is no problem of getting the server "stuck" due to extension rate limits.
Improves the image request logic by making it possible to check if an image is cached.
In case an image is cached, it does not need to be put into the image queue because it won't be sent to the server.
In case the previous page in the history should be ignored, the back button just went back to the root page (library).
Instead, it should try to go back to the next page in the history until there is no page to go back to anymore.
With 12ef012e4b this has no benefit anymore, because the app now always checks if authentication is enabled by the server first before any other request can be sent.
Caused issue for some languages, e.g., for all the different chinese languages, which are not all specified in the "IsoLanguages". These languages all incorrectly used the standard native chinese name which resulted in multiple different source groups with the same group name.

Previously, the drag-scroll implementation used incremental relative positioning
which accumulated rounding errors over time. This caused the mouse cursor to
gradually drift away from its original position during prolonged drag operations,
particularly noticeable on slower hardware or systems with lower frame rates.
The fix switches from cumulative delta updates to absolute positioning:
- Track initial mouse and scroll positions when drag starts
- Calculate scroll position as: initialScroll - (currentMouse - initialMouse)
- This ensures the visual position remains locked throughout the entire drag
This change eliminates drift by avoiding cumulative floating-point
errors that occurred with the previous += approach.
1. Inverted Logic: The code adds the mouse delta to scrollLeft/scrollTop, but this is backwards. When you drag right, you want the content to move left (scroll increases), and vice versa.
2. Cumulative Rounding Errors: Using += with floating-point deltas accumulates rounding errors over time, especially on slower hardware where mousemove events may be processed less frequently or with more delay.
3. Frame Rate Dependency: On slower hardware, if the browser can't keep up with all mouse events, some movements get skipped, but the positions still update, causing the reference point to drift.
