SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***

STEPS TO REPRODUCE
1. Go to an album with more than 100 images, or view a search result with more than 100 images
2. Open an image in preview mode (e.g. by double-clicking the image)
3. See if the album thumbnail scroll frame (default position is above the image preview frame) has the current image visible and highlighted

OBSERVED RESULT
If I click to preview any image from the 1st to the 100th, the thumbnail is visible and highlighted. If I click to preview an image past the 100th, the thumbnail scroller will not automatically scroll past the 100th image; the previewed image IS highlighted, but it is not visible in frame unless you manually scroll the thumbnail frame.

EXPECTED RESULT
The currently previewed image should have been scrolled into view -- preferably centered in the scroll frame if possible (if it isn't at the very beginning or end of the album).

SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma:
(available in About System)
KDE Plasma Version:
KDE Frameworks Version:
Qt Version:

ADDITIONAL INFORMATION
If I have manually scrolled to see the currently previewed image in the thumbnail scroll frame, and if a new file is then added to the album while previewing the image, the thumbnail scroll frame will scroll back to a different position. This probably only applies when previewing an image past the 100th image of the album.

Forgot to mention: This is happening in Windows 11, but I think it also happened in Windows 10.
