Blueprint Viewport Not Updating When Destructible Mesh Component is Assigned a Mesh

When you add a Destructible Mesh to a Destructible Mesh Component inside of a blueprint, the viewport is not updated with the new mesh. If you add the blueprint to the level and then open the blueprint again, the mesh will appear.

Found in 4.11.1 binary. Reproduced in 4.10.4 binary and Main CL 2945174

Regression? No, this also occurs in 4.10.4.

1. Open the editor
2. Create a new actor blueprint
3. Give the blueprint a destructible mesh component (I set it as the root)
4. Create a destructible mesh by right-clicking on any static mesh and selecting the Create Destructible Mesh option
5. Go into your actor blueprint and set the Destructible Mesh Component to use the newly created DM

Result: The DM does not show up in the viewport.

Expected: The viewport would update with the new DM.
