Error: unable to parse Dockerfile: unexpected token comment

[akkadaya]

Describe the bug

dprint-plugin-dockerfile version: 0.3.0

Input Code

RUN \
# Print Hello World!
echo 'Hello World!'

Expected Output

RUN \
  # Print Hello World!
  echo 'Hello World!'

Actual Output

❌ Error:

[ERROR] Error formatting text. Error: unable to parse Dockerfile: unexpected token comment

RUN \
# Print Hello World!
echo 'Hello World!'

Additional Information

if I move the comment up or down, it'll work fine but it breaks only when the comment sits under RUN \ directly

# Print Hello World!
RUN \
echo 'Hello World!' \
# Print Hello World!
echo 'Hello World!'

⚠️ BUT, the comment and the subsequent code will not be formatted!
Output:

# Print Hello World!
RUN echo 'Hello World!' \
# Print Hello World!
echo 'Hello World!'
