Description David 2021-11-20 22:29:12 UTC 
SUMMARY
In the latest versions of Okular, if I configure it to open new files in tabs, I cannot open the same file twice to show it in two tabs, which used to be possible in earlier versions.

STEPS TO REPRODUCE
1. Launch Okular, go to Settings -> Configure Okular -> General -> Program features -> check "Open new files in tabs".
2. Open some PDF file in Okular.
3. Try opening the same PDF file again in Okular.

OBSERVED RESULT
Nothing happens.

EXPECTED RESULT
Should open the same file in a new tab.

You can change that behaviour in the settings dialog if you don't like it.

Got it, but why would you make that option the default? It's very common if you are reading something like a scientific article to be constantly looking at different sections of the document simultaneously (for example to see the references and figures), and for me at least the only reason why I enable tabs in okular is to have the same document openened many times.

Reading scientific articles is probably not the most common use case for Okular
Comment 4 Laura David Hurka 2021-11-22 20:17:22 UTC 
I have re-enabled this option for me, so I do not open more and more tabs of the same document, only because I am to lazy to search through all the tabs whether I have the document already open. But sometimes I want to open a second tab of one long document for the use case described.

Can we add a menu action “Duplicate tab”? Many web browsers have this action too.

Sure, doesn't seem like it should be a lot of code or make maintainability harder
