From my website, I'm linking several sections within a PDF document using URL in format http://www.example.com/Document.pdf#nameddest=sectionXY (as discussed e.g. here). My PDF document is manually created from a DOCX document using the "PDF export" function in MS-Word 2016. The labels are marked as MS-Word bookmarks in the source document.
Unfortunately, the PDF viewer in the web browser scrolls to the proper section only in the Google Chrome. In other browsers (FireFox, IE 11 or Edge) the PDF document is always opened on the first page.
I'm sure my solution used to work several years ago both in Chrome, FireFox and IE.
Is there any way to make it work at least in Chrome and FireFox? I'm able to use another converter (or even some PDF library) but I cannot afford to have my source document in any other format than DOCX. I'm even able to mark my "labels" another way than using MS Word bookmarks.
