Deluge doesn't stay in the same workspace when a magnet link is clicked in a browser

Status changed to 'Confirmed' because the bug affects multiple users.

A workaround is to disable 'focus add dialog' in preferences, which will prevent the application switching workspaces.

I am not sure what the best practice is for dealing with workspaces but I think, based on observing other applications, the first expected outcome should be modified to the following:

    If another workspace is active then do not switch workspace but indicate the application needs attention in the launcher.
    User then switches to the application needing attention by clicking on the icon in launcher which also switches workspace.

The fix for this outcome would be to only focus the Add Dialog if the Deluge workspace is active.

The second outcome might be more correct when it involves dialogs. For example I have seen Thunderbird displaying a new message dialog on the active workspace while the application remains in another. The Deluge fix for this would be to disable set_transient_for(mainwindow) in the Add Dialog however this may result in unintended consequences for other users so will need tested before implementing.

Thanks for providing information on how other applications handle this situation. I agree that the Thunderbird way is more suitable. And it is also good to keep UI behavior consistent with other applications. I have modified the bug description.
