Argument ranges have a start position later than the end position

import { DockerfileParser } from 'dockerfile-ast';

let dockerfile = DockerfileParser.parse("RUN \"\\\n  \\\n\\\"");
let instruction = dockerfile.getInstructions()[0];
console.log(instruction.getArguments().length);
for (const arg of instruction.getArguments()) {
    console.log(arg.getRange());
}

dockerfile = DockerfileParser.parse("RUN \"\\\n\t\\\n\\\"");
instruction = dockerfile.getInstructions()[0];
console.log(instruction.getArguments().length);
for (const arg of instruction.getArguments()) {
    console.log(arg.getRange());
}

Notice here how the second argument has a range with a start position later than the end position.

{ start: { line: 0, character: 4 },
  end: { line: 1, character: 2 } }
{ start: { line: 2, character: 0 },
  end: { line: 1, character: 2 } }
2
{ start: { line: 0, character: 4 },
  end: { line: 1, character: 1 } }
{ start: { line: 2, character: 0 },
  end: { line: 1, character: 1 } }

The Dockerfiles should look like this instead and not what was in the original post.
