Is rendering the same Page multiple times within the same Document supported?

[esafford]

I'm trying to add a left-hand sidebar to my React-PDF implementation (similar to the pdf.js demo), and I'm running into what appears to be a race condition around rendering the same page multiple times within the same <Document />.

I found a codepen from a separate issue, and made a quick fork that I should be highlighting the issue. I see the issue most often with page 14 - so, for example, if you page back and forth between pages 13 and 14, you'll occasionally see the first page 14 rendered (when it should be rendering 4 copies of page 14).

Obviously, I'd prefer not to load a separate <Document /> component to handle the sidebar rendering. Is there another recommended approach for this, or should I be filing this as an issue?

Thanks! 😄

Found even easier way to reproduce this: just resize window when you're on page 14. Wonder if this has to do with PDF.js worker being unable to handle rendering the same page twice at the same time...
