"UnlinkFromLibrary" action not triggered when double click on a symbol and click to "Unlink from Library" button.

If you unlink a symbol via opening dialog when double click on a symbol, action not triggered.

If you unlink a symbol via popup list in inspector panel, everything is fine.

This would be really valuable to solve. What is Sketch doing under the hood that means this action isn't triggered?
