Thumbnail highlight skips pages with variable PDF page sizes

Description
When viewing a PDF document with a vastly varying number of page sizes, such as:
with the thumbnail viewer opened on the left, then the thumbnail viewer highlight does not always follow the scrolling in the main viewer window.
When scrolling from one oversize page to another oversize page (past a smaller out-of-view page), then the highlight in the thumbnail viewer will skip from page N to page N+2.
Reproducible (100%):
- View page 50 (very wide landscape page)
- Scroll to right-hand-side.
- Scroll downwards until only empty space (no page) is visible
- Thumbnail highlight stays on page 50
- Scroll downwards some more
- Thumbnail highlight jumps to page 52
Ideally the page highlight should either keep pace with the current page (even if off to one side), or the highlight be deactived when all pages are outside of the viewing frame.
