pages panel missing pages on the last row of pages

When I open a multipage pdf (80 pages maybe) and turn on the pages panel certain widths of the pages panel cause the last row of pages to be just barely visible (easy to miss).

For instance I have a 309 page pdf open with the pages panel on and with the panel width set so that I have 2 columns and when I scroll to the bottom of the pages panel the last row I see clearly is for pages 307 and 308, but if I look really close I just do see the top of the page for 309. It seems to vary for the number of pages and width (number of columns) of the pages panel.

Anyone else experiencing this?
Anyone have a fix?
I know the workaround is to keep adjusting the pages panel width until I see all rows, but that could be an adjustment each time each of my users opens a different pdf file.

Thanks,
Tate
