Deferred Actions : When a tag is propagated from an entity via 2 processes , blocking 1 process removes tag propagated from another process

1.Create a lineage as attached in the screenshot (i.e) tag propagated from a source using 2 processes to a target 

2. Add a tag to t3 , now the tag is propagated to t4 via both process1 and process2.

3. Now block the propagation from t3 to process1.

4. Expectation is that , tag will be propagated via process2 to t4. But the  propagated tag is removed from t4
