Not clamping the page number, no ellipsis for many pages, not resetting page on filter change, no disabled state for prev/next at boundaries, not updating total pages on data change, and no loading state for server-side pagination.
Because the filtered data may have fewer pages. If the user is on page 5 and the filter only has 2 pages, they see nothing. Reset currentPage to 1 when filters change to ensure the user sees valid data.
Clamp the page number: currentPage = Math.max(1, Math.min(requestedPage, totalPages)). This ensures the page is always between 1 and the total number of pages.
