When I click an inter-PDF hyperlink in Okular, a new file in the same window opens. But after this Back button does not work. It makes inter-PDF hyperlinks useless and even harmful (because I can't return back). We probably should make Back button to work between different PDF files or make inter-PDF links to open a new window, or invent something else. Probably it applies not only to PDF, but also to other file formats. Reproducible: Always
Another possible option is to open such links in a new tab (dependently on the Okular settings).
Please attach some files to help reproduce this if you have them at hand
No answer for years
The current version (0.26.1) of Okular opens links either in a new window or a new tab. Thus the bug does not harm anymore. I consider it fixed.
