Issue on the first enter

[lucand]

When you enter the editor for the first time, and click on the connection between nodes, pressing delete key doesn't fire delete event, although connection is selected(highlighted).

How strange... a node yes, but a connection no...

You can fix it with this right now:

   editor.on("connectionSelected", () => {
      if(document.activeElement !== editor.container) {
        editor.container.focus();
      }
    })

Fix works fine, thanks for help.
