Description
when n_genes is set to a value (such as 2000), and pts=True, then sc.tl.rank_genes_groups will compute the fraction of cells expressing the genes, but the output includes all the genes, not just the 2000 genes.

Research direction
Start at the sc.tl.rank_genes_groups entry point and reproduce the behavior with n_genes=2000 and pts=True. Trace how the selected genes and expression fractions are returned, then verify that the output contains only the requested number of genes rather than all genes.
