When searching the above pdf for the phrase 'acute' the second hit hightlights the nearby word ' especi'.  Almost certainly this is the same issue that I raised in #5667 

However, when examining the generated html you can see that the highlighted text is incorrect - it contains the text ' especi' and not the search term 'acute' - it is not a positioning issue.  (see screenshot).

I am using Chrome 39, windows 8.1 x64 and pdf.js 1.0.1093

        if (
          pageNumber >= 1 &&
          pageNumber <= linkService.pagesCount &&
          pageNumber !== linkService.page &&
          !linkService.isPageVisible(pageNumber)
        ) {
