Hey!

I found what I believe is a little bug with regards to isorts combine-as-imports, as it seems to act contrary to its definition in some cases.

Sample reproduction code:

from json import detect_encoding
from json import dump
from json import dumps as json_dumps
from json import load
from json import loads as json_loads

Quite a bad example of "real world code", but there is a genuine use case behind this. The random imports are for the sake of showing the problem. Note that running isort with profile = "black" and force-single-line = true doesnt change this file

--fix while using combine-as-imports = true

$ ruff ruff_test.py --select I001 --fix
<no output>

$ cat ruff_test.py
from json import detect_encoding
from json import dump
from json import dumps as json_dumps
from json import load
from json import loads as json_loads

--fix while using combine-as-imports = false

$ ruff ruff_test.py --select I001 --fix
Found 1 error (1 fixed, 0 remaining).

$ cat ruff_test.py
from json import detect_encoding
from json import dump
from json import load
from json import dumps as json_dumps
from json import loads as json_loads

Ruff settings:

[tool.ruff]
line-length = 125
target-version = "py38"
select = ["E", "I", "F"]

[tool.ruff.isort]
force-single-line = true
combine-as-imports = true  # This line config will be added/removed according to the steps above

Ruff version:

ruff 0.0.255
