Shortcuts not working for floating outliner window

Steps to Reproduce

  1. Create a new project (ensure that the outliner is docked in the main window)
  2. Create an actor in the viewport *
  3. Drag the outliner so that it becomes a separate, floating window
  4. Select the created actor in the outliner
  5. See that most shortcuts for actor editing stop working, e.g. ctrl + c, ctrl + v, ctrl + d, ctrl + b. Shortcut ctrl + e still works.

* When clicking the actor in the outliner at this point, you can see that all shortcuts listed in step 5 work.
