Links to members on self fail when using -groups

[scabug]

Run scaladoc -groups for the following class:

/**
 * See [[boppy]].
 *
 * @groupname stuff Stuff
 */
trait Bippy {
  /**
   * Boppy.
   * @group stuff
   */
  def boppy: Int
}

Clicking on the link to 'boppy' from the trait header does not work because there are duplicate elements with same id for that anchor. This duplicate elements are inside the hidden 'allMembers' element that only shows up with grouping:

<?xml version="1.0"?>
