some ops like RGWPutCORS, RGWDeleteCORS, etc. handle writes to the bucket instance like this:

  op_ret = retry_raced_bucket_write(this, s->bucket.get(), [this] {
      rgw::sal::Attrs attrs(s->bucket_attrs);
      attrs[RGW_ATTR_CORS] = cors_bl;
      return s->bucket->set_instance_attrs(this, attrs, s->yield);
    });

if retry_raced_bucket_write() detects a race and reloads the bucket info, 's->bucket_attrs' doesn't get updated with the new bucket attributes

other ops handle this correctly by using s->bucket->get_attrs() instead:

  op_ret = retry_raced_bucket_write(this, s->bucket.get(), [this, y] {
    rgw::sal::Attrs attrs = s->bucket->get_attrs();
    attrs[RGW_ATTR_TAGS] = tags_bl;
    return s->bucket->set_instance_attrs(this, attrs, y);
  });
