Import input as references not working when using World Outliner Input

[schauko]

steps to replicate:
create a HDA containing just an input + output
import that hda in unreal
place it in the scene
set input mode to "world outline input"
check "import input as references"
pick meshes in scene
-> just the default houdini logo mesh will appear
(unchecking import as references imports the meshes, but not as a reference but as a houdini generated mesh)
