Description

If we transfer balance of buffer1 from allocator1 to allocator2, onRelease() should be called from allocator1.listener as well as the case that buffer1 is closed without transferring.

Research direction

Review the allocation and ownership-transfer implementation, then inspect PR #11800 for the existing work. Done means allocator1.listener receives onRelease() when buffer1 ownership transfers to allocator2, as it already does when buffer1 is closed without transferring.
