When embedded strings are moved, not all the embedded bytes are copied over to the new embedded string. This shows itself when
an embedded string has more than 16 characters.

For example:

r = Ractor.new {
  foo = receive
  puts foo
  foo
}
obj = "12345678" * 3
puts obj
r.send(obj, move: true)
r.take

123456781234567812345678
1234567812345678
