Drag'n'drop only works sometimes on Linux

Drag'n'drop to load files only works sometimes on Linux, i.e. it usually takes several attempts until Knossos successfully loads something through drag'n'drop.

The dropped url is printed in the console, can you check it when it doesn’t work?

[fabiansvara]

It is not printed when it doesn't work. In fact, when you click on a file, hold down the mouse button, and then move the cursor in and out of the Knossos window several times, sometimes the path will be printed, sometimes not.

I think it has to do with the fact that the annotation widget is hovered before and ›steals‹ the DnD event somehow (because of DnD implementation to move selected nodes to another tree).

i think this has the same reason as https://github.com/knossos-project/knossos/issues/462
