[F401] missing errors

[tony-sanchez]

Summary

Hi,

I'm occasionally struggling with the F401 rule, I managed to reproduce the issue with the following example.

Given this file, named ruff_F401.py:

def my_method():
    import package.a.b.c.d.module_a
    import package.a.b.c.d.module_b
    import package.a.b.e.module_c

When I run ruff --isolated check ruff_F401.py I get the following report:

ruff_F401.py:4:12: F401 [*] `package.a.b.e.module_c` imported but unused
  |
2 |     import package.a.b.c.d.module_a
3 |     import package.a.b.c.d.module_b
4 |     import package.a.b.e.module_c
  |            ^^^^^^^^^^^^^^^^^^^^^^ F401
  |
  = help: Remove unused import: `package.a.b.e.module_c`

Found 1 error.
[*] 1 fixable with the `--fix` option.

If I provide the --fix argument, then the 3 imports are replaced with a pass.

Expected behaviour:

I'd expect a F401 error to be reported for each of the 3 lines.

Thanks for the report! This looks like a duplicate of #4656

There is a PR out for this (#13965), but maybe we can do some more work to help get it over the line.
