Wrong position of nodes when modifying LineString

[FrancicoVerdu]

Describe the bug

I have a LineString of about 200 grid elements, when I paste it into the Nebula Editor it is rendered correctly, but when I try to modify the line by adding a new position it is not always generated correctly because editContext.positionIndexes has a wrong value.

Actual Result

Correct location of the new node but misplaced in the array of positions

Expected Result

correct location of the new node and well placed in the array of positions.

Reproduce Steps

• paste the GeoJson in the Nebula Editor GeoJson
• centre the map in the middle of spain to locate the geometry
• select the modify tool of Nebula Editor GeoJson
• create a new node between two points
• move the node to see the bug (not 100% of the time but most of the time)

I have been able to verify that this error only occurs when the coordinates have a third component, even if it is equal to 0. Unfortunately, I need this third coordinate because in my project it will not always be 0.

By "third component" do you mean using vertical datum apart from the longitudes and latitudes?

[FrancicoVerdu]

He podido comprobar que este error solo ocurre cuando las coordenadas tienen una tercera componente, aunque sea igual a 0. Lamentablemente necesito esta tercera coordenada porque en mi proyecto no siempre será 0.

¿Por "tercer componente" quiere decir usar datum vertical además de las longitudes y latitudes?

Indeed, when the coordinates are in the format [ longitude, latitude, elevation]
