Characters can fall through a rotating sprite that has been scaled

A scaled sprite does not appear to consistently maintain its collision for characters near its edges. I'm not certain whether this has anything to do with the character being in a fall state, but that seems to be when it occurs.

The user has provided a test project in the AH post.

1. Launch: UE4Editor.exe
2. Create a new 2D Side Scroller project
3. Select the Ledge sprite below the Player Start
4. Scale the platform to 5.0 along the X axis
5. Click "Blueprint/Add Script" button, with Ledge sprite still selected
6. Save Ledge sprite as Blueprint
7. Set RenderComponent of Ledge sprite to Moveable, in Details panel
8. Open Event Graph of Blueprint
9. Open attached txt file and copy then paste into Blueprint window
10. Connect the platform component to the Target input
11. PIE
12. Run to the right towards the edge of the platform as it rotates

Result:
The character will get near the edge of the scaled sprite and then fall through it

Bad collision between falling pawn + moving platform?
