Bug in bookmarklets?

I noticed that the bookmarklets that I installed in Safari work properly only if DT is already opened: if not, using the bookmarklets (both of them) opens DT, but does not put anything in it. I have to click again and redo the action with DT open.
If I use other ways of importing things, like the scripts or the service menu, DT opens and already has the right thing put in it.
Is that normal and/or unavoidable? Or maybe by design?

It’s indeed a bug, thank you for reporting it. The next release will fix this.
