PrimitiveType.union accepts fixed_len_byte_array fields with different lengths when strict mode is on

[asfimport]

The following two schemas probably shouldn't be allowed to be union-ed when strict schema-merging mode is on:

message t1 {
  required fixed_len_byte_array(10) f;
}

message t2 {
  required fixed_len_byte_array(5) f;
}

But currently t1.union(t2, true) yields t1.
