In an unique instance, added node has no links, resulting in no path

[nemosmithasf]

I've stumbled upon a very specific instance where the script breaks, it's fascinating because if I move any of the coordinates just slightly, it works again. See the video below:

visibilityGraphBug.mp4

When we try to find a path between origin and destination, it's unable to find a path (the path leading to nowhere at the beginning of the video is a visual bug indicating "can't find path")

But if we change any of the coordinates in Origin or the Boundary just a bit, it works again.

I've narrowed it down to essentially origin not having any links in its graph-node (because for some reason processPoint() never detects anything as isVisible)

Here are the inputs for reproducing:

Origin

[-96.75315856933595, 33.047810073472085]

Boundary

{
            "type":"Feature",
            "properties":{
               
            },
            "geometry":{
               "type":"Polygon",
               "coordinates":[
                  [
                     [
                        -96.81838989257814,
                        33.03457126491144
                     ],
                     [
                        -96.78405761718751,
                        33.047810073472085
                     ],
                     [

                     ],
                     [
                        -96.77169799804689,
                        32.98390006815716
                     ],
                     [
                        -96.81838989257814,
                        33.03457126491144
                     ]
                  ]
               ]
            }
         }

Destination (this doesn't actually matter, but including it for completeness)
