3.0 regression: Drag&Drop of tracks to playlist does not work while a track is playing
On VLC git master, I cannot drag & drop tracks from dolphin while a different track is playing - checked on Mageia 7 x86-64 and Fedora 26 x86-64. It works fine when no track is playing, and worked fine in the past in the git master.
See https://github.com/shlomif/vlc-drag-and-drop-bug-1 for a reproducing testcase. I'll try to do a git bisect for it soon.
