Adjusting properties of a Blueprint instance's components in the level does not update references to the properties in the BP's Construction Script

Adjusting properties of a Blueprint instance's components in the level does not update references to the properties in the BP's Construction Script. Note: this would work in 4.8.3.

Reproduced in 4.9.2 binary and Main (CL ). This is a regression: does NOT occur in 4.8.3.

1. Open any project
2. Create a new Actor Blueprint
3. Add a Cube component
4. In the Construction Script, Cube Component > Get World Scale > Print String
5. Drop the BP in the level
6. In the Details panel, select the Cube Component for the Actor
7. Change the Scale

Result:
The Construction Script does not update the value printed to reflect the change to the component in the Details panel

Expected:
The Print String in the Construction Script updates to match the instance's component details
