Fix sanitizing config lines (#50553)

Previously, the index got out of sync with the actual config list. Invoked with lines:
  - bad
  - first
  - bad
  - second
the sanitization would first delete index 0 and then index 2, which would result in the output
  - first
  - bad
By reversing the list, we avoid that problem (though a filter() would be nicer)
