The intersection of two lines is not on these two lines

question:
hello, Use the Turf intersection function to calculate the intersection point of two lines, and then use Turf to calculate that the intersection point is not on the two lines.

function inter() {
  const point = turf.lineIntersect(
    {
      type: 'LineString',
      coordinates: [
        [109.97765856266103, 30.90174439429663],
        [109.99221445294349, 30.834370219066155],
      ],
    },
    {
      type: 'LineString',
      coordinates: [
        [109.99221445197468, 30.83437021906627],
        [109.9776585755893, 30.9017443942969],
      ],
    }
  )
  const result1 = turf.booleanPointOnLine(point.features[0], {
    type: 'LineString',
    coordinates: [
      [109.97765856266103, 30.90174439429663],
      [109.99221445294349, 30.834370219066155],
    ],
  })
  const result2 = turf.booleanPointOnLine(point.features[0], {
    type: 'LineString',
    coordinates: [
      [109.99221445197468, 30.83437021906627],
      [109.9776585755893, 30.9017443942969],
    ],
  })
  console.log(result1, result2)
}

Start by running the provided JavaScript example and inspect Turf's lineIntersect and booleanPointOnLine entry points. Reproduce the result with the supplied coordinates, then determine the expected precision behavior for the reported intersection. Done means the behavior is corrected or clearly documented, with coverage for this case.
