error on creating nodes in collapsed shader graph

Reported it to Epic Games but posting it here too so it might not get lost that easily.

  1. Create new shader
  2. Create any node in it (for example just scalar value (1))
  3. Select that node, right mouse click and “Collapse nodes”
  4. Inside collapsed nodes try one of two things:
  • create component mask with Shift-C hotkey
  • create Vector4 Parameter (hotkey 4 / ConstantVector), right click it and hit “Convert to Parameter”

Results:
the component mask or Vector4 Parameter will be created in the main shader graph, not inside the collapsed node

Expected:
expected them to be created in the collapsed node graph too
