Formatting with extension adds extra lines after comments

[JasonKChow]

When formatting using ruff-api, the extension's formatter adds newlines after comments. This appears to only happen on Windows.

This snippet of example code when formatted via the extension will continually add newlines after every line of the block comment and new lines after the single line comment.

points = [[10, 10], [10, 11], [11, 10], [11, 11]]

manual_dummy_config = f"""
[common]
lb = [10, 10]
ub = [11, 11]
parnames = [par1, par2]
outcome_types = [binary]
stimuli_per_trial = 1
strategy_names = [init_strat]

[init_strat]
generator = ManualGenerator

[ManualGenerator]
points = {points}
seed = 123
"""

# reading config
print(manual_dummy_config)

gets formatted into:

points = [[10, 10], [10, 11], [11, 10], [11, 11]]

manual_dummy_config = f"""

[common]

lb = [10, 10]

ub = [11, 11]

parnames = [par1, par2]

outcome_types = [binary]

stimuli_per_trial = 1

strategy_names = [init_strat]



[init_strat]

generator = ManualGenerator



[ManualGenerator]

points = {points}

seed = 123

"""

# reading config

print(manual_dummy_config)

Even worse, if formatted again, it'll add even more newlines.

The VSCode ufmt output is as follows:

formatting in-process
CWD Linter: ...\ae\aepsych
formatting with:  ufmt==2.8.0  black==24.4.2  libcst==1.5.1  ruff-api==0.1.0  usort==1.0.8.post1
formatting complete

When using ufmt CLI separately, this does not happen. The CLI reports nothing needs to be formatted in a file containing the above snippet.
