Paper2D Set Sprite function in Construction requires mobility to be set to Movable

If you set up a default Sprite in an Actor BP and in the construction script set the sprite to an Editable Sprite Variable, in order for the new sprite to show up mobility of Sprite and BP must be Movable. This is not the case in 4.7.6.

Quick Repro with attached Project

1. Open QAGame Editor
2. Create a New Actor BP
3. Add a Paper2D Sprite to BP Components
4. Assign PaperSprite'/Paper2D/DummySprite.DummySprite' to the Component
5. In the Construction Script, Get the Paper Sprite Component
6. Off the Got Component, Set Sprite
7. Add an Editable Paper Sprite Variable
8. Connect the new Variable to the New Sprite Input
9. Compile and Save
10. Place the BP into the level
11. In the BP Details panel set New Var 0 to a Different Paper Sprite
12. In the BP, Change Mobility of teh Paper Sprite Component from Movable to Static

RESULTS: In the Level, the BP no longer shows the new sprite set by the Construction Script

EXPECTED: New Sprite shows up despite the Mobility.
