What went wrong?

After scrolling down in the library page, pressing the filter button does not show the filter panel.

The filter panel only becomes visible again after scrolling back to the top of the library page.

It seems like the filter panel/window may not be properly anchored to the visible viewport or to the filter button position after the page has been scrolled.

The same behaviour is observed on the Tools, Series, and Author menu.

Steps to reproduce

1. Open a library page.
2. Scroll down the library page.
3. Press the filter button.
4. Observe that nothing appears.
5. Scroll back to the top of the library page.
6. Press the filter button again, or observe where the filter panel appears.

Expected vs actual behavior

Expected behaviour:
The filter panel should appear near the filter button or within the visible viewport, regardless of the current scroll position.

Actual behaviour:
After scrolling down, pressing the filter button appears to do nothing. The filter panel only becomes visible after scrolling back to the top, suggesting it is not anchored correctly.
