Nullable embedded schema behaves differently on Realm 12 and 11

[andreyukD]

How frequently does the bug occur?

Always

Description

Realm 11.9.0 and 12.3.1 (I suppose it since 12.0.0) have different behavior when setting the embedded object field to null.
While 11.9.0 allows us to do it, 12.3.1 doesn't set null to an object field. Will it be fixed, or are these new validation constraints?
