Disabling "Should Be Visible" On a Streaming Level Resets Variable Values

When disabling "Should be Visible" of a stream level and then enabling it again, the values of variables in a Blueprint that has been placed in a stream level maintain their value in PIE but reset the values in Standalone.

It is unclear which one of these is intended functionality, but there is an inconsistency.

1. Open the attached project
2. Play in Standalone
3. Press 1 to Load Stream Level
4. Wait for the variable to be set to 5 and printed to the screen after ~5 seconds
5. Press 2 to hide the streaming level
6. Press 3 to make the level visible again

Result: In Standalone, the variable is reset to 0 when the level is made visible again

Expected: The variable would retain its value
