Try to Cut initializer and Paste it into another class. Initializer is properly removed from source class, but into target class is inserted only empty body!!!
[Svata] The origin of the bug predates FCS. There`s bad ordering of operations in Paste implementation on ClassElement nodes so the initializer is deleted first, then inserted at the new place -- but
its body is lost.
Resolved for 3.4.x or earlier, no new info since then -> closing.
