Thank you for the bug report.  But this is not a bug.  That is the
correct and desired behavior.  That is the way it is supposed to work.
This is documented in the manual.

  $ info coreutils 'rm invocation'

  `-f'
  `--force'
       Ignore nonexistent files and never prompt the user.  Ignore any
       previous `--interactive' (`-i') option.

This is core behavior and is also standardized across all Unix
systems.  Here is a pointer to the online standards documentation.
