Bulk Edit via Property Matrix gets disconnects from blueprints after BP compile

"If you ever compile a Blueprint that you have opened in the Property Matrix, it will lose its connection and variables you change in the blueprint won't be reflected in the Matrix and vice versa leading to a indeterminate state of what gets saved when you save the Blueprint."

Confirmed in Main @ CL 4845042

1. Right Click on a Blueprint, Select Asset Actions -> Bulk Edit via Property Matrix
2. Pin a property
3. Open the Blueprint in the Blueprint Editor
4. Observe that changing values on either side are instantly reflected in the other window
5. Compile the BP

Result: Properties are no longer mirrored

Workaround: Close and reopen the property matrix
