Extract returns wrong line in case of narrow angles in line

[sookoll]

I had situation where I need to find line segment from start to certain point along line (with snapping along line). It works fine with wide angles but with smaller than 90 degrees it will "jump" to previous line segment. I got fraction from locateOnLine.

Turf for example, handles it correctly. Also input as starting and ending point is better approach than blurry fraction.

Hello @sookoll

Do you have a jsfiddle to test this issue ?
