Colliding seven styles causes abnormal padding

If there is a multi item that creates a table in the node form the table has wrong paddings.

fieldset .fieldset-legend {
  padding-left: 15px;
}

fieldset .fieldset-wrapper {
  padding-right: 13px;
  padding-left: 15px;
}

These may need to be set to 0, but I guess the root cause is any other issue as we have not seen this without Inline Entity Form on these entityreference fields.
