    Description

      Given a CSV file of this form:

      fstring
      "one"
      "line"
      

      a reproducer for the incorrect behaviour is the following (both {{Count}}s should be 2):

      root [0] auto rdf = ROOT::RDF::MakeCsvDataFrame("test.csv")
      root [1] *rdf.Count()
      (unsigned long long) 2
      root [2] *rdf.Count()
      (unsigned long long) 0
