fdo#47355: partially revert c5a8a2c3cbcee0175127a0662e3d820ea4deea22

- that commit claimed to fix i#84870
- however that example document _still_ loops for me on current master
  even with the change
- this caused the fdo#47355 regression in addition
- thus reverting to heal fdo#47355, expecting i#84870 unchanged as broken
  before and in need of a proper fix
