Cannot delete edge in StrictMode

[alpeshgaglani]

I am using version 2.1.2. Due to a variety of security related concerns, our schema is defined in the strict mode = true. There's a specific case where I cannot delete edges. Here's how to repro:
create class V1 extends V
create class V2 extends V
alter class V1 strictmode true
alter class V2 strictmode true
create class V1ToV2 extends E
alter class V1ToV2 strictmode true
create property V1ToV2.out LINK V1
create property V1ToV2.in LINK V2
create property V1.out_V1ToV2 LINKLIST V1ToV2
create property V2.in_V1ToV2 LINKLIST V1ToV2
create vertex V1
create vertex V2
create edge V1ToV2 from (select from V1) to (select from V2)
create vertex V1
create edge V1ToV2 from #42:1 to (select from V2)
delete edge V1ToV2 from #42:1 to (select from V2)

Error: com.orientechnologies.orient.core.exception.OValidationException: The field 'V2.in_V1ToV2' has been declared as LINKLIST but an incompatible type is used. Value: [V1ToV2#44:0{out:#42:0,in:#43:0} v1]

I believe this repros if two vertices have an outgoing edge to a third vertex, and if you try to delete one of those edges.
I have been struggling with this for a bit, and see a related issue #3534, which was closed as invalid. But it's clearly the case for me. Any help in fixing this is greatly appreciated!

Found the problem: on edge removal the setting graph.isAutoScaleEdgeType() is not considered, and a collection is transformed on single value. Fixed in 2.1.3.
