Inconsistent SQL results when using View with UNION-ALL and table function

Question

Can any of you please execute the below scripts and check the output. In the table type variable, I am adding 4 distinct object ids, where as in the result, I get only the row pertaining to last id in the table type variable. Same row is returned 4 times (4= number of values in the table type).
This scenario is occurring in our product with a SQL with exactly same pattern. I could simulate the same issue with the sample script I have provided.
Database version: 11.2.0.3 Enterprise Edition, Single node
Thank you.
