Comment (by felipeelia):

 I tried to reproduce the problem but I could not (sorry if I missed
 something :-) )

 Summarizing my findings, in `wp_check_filetype_and_ext()` we deal with two
 mime types: one from `wp_check_filetype()` and another from
 `finfo_file()`.

 As @bradshawtm pointed out, `finfo_file()` will indeed return `'text/csv'`
 but so will `wp_check_filetype()`, and adaptations are only needed when
 those two don't match.

 Happy to work on the unit tests if I missed something and can start
 reproducing the problem.
