movies about a real person aren't listed under that real person's filmography

I was interested in movies about Julius and Ethel Rosenberg. On Ethel Rosenberg's page (https://www.imdb.com/name/nm0742211/?ref_=hm_rvi_i_1) it does not show a popular movie about them, "Judgment: The Trial of Julius and Ethel Rosenberg" (https://www.imdb.com/title/tt0391258/?ref_=hm_rvi_i_2). Perhaps there's not a category for fictionalized biopics under that person. Or perhaps this is a one-off mistake. 

I LOVE IMDB!!!
