I'm not sure about this. At least on Linux, where I just tested - I have in-document jump links working across Chromium, Firefox, Evince, Okular, and even KOReader. Tested on a random arxiv PDF[0]. Chromium and KOReader don't highlight links, but clicking them still works.
I didn't test on Linux, since we only permitted BYO Linux machines exceptionally.
And the PDF feature support landscape may have changed in the last year, since it was Q1 of last year (2022), I believe, when I last checked the in-browser PDF viewers in Google Drive, OneDrive, HubSpot, and Chrome for macOS and Windows. I suppose it might have been longer since I did the actual comparative testing.
