[poppler] pdftohtml: "link to page n"

https://ars.els-cdn.com/content/image/1-s2.0-S1550413116304211-mmc1.pdf

I see things like "link to page 11" in the output of the following command.

```
pdftohtml -i -stdout 1-s2.0-S1550413116304211-mmc1.pdf  | sed 's| | |g'
```

But I don't see the text "link to page 11" in the original pdf.

The pdftohtml output of the following pdf file does not have things
like "link to page 11".

Why "link to page 11" is generated for
1-s2.0-S1550413116304211-mmc1.pdf? Is there a way to disable it?
Thanks.
