Visual bug with freeform Light2D overlapping itself

Question

I'm using the new experimental light 2D component (so I understand if there's currently no solution) and I'm getting an issue where the freeform light is overlapping itself, creating noticeable artifacts:

As you can see in the second image, the bounds of the light is intersecting itself. I've tried using AlphaBlendOnOverlap but that just reduces the effect slightly rather than fixing it.

The effect I want is: Desired effect I can only get this if I don't use tight corners convex corners, which unfortunately I intend to use a lot of.

I never found a real solution, but I was able to get a reasonable result by creating really long, thin shapes with the light's polygon:

This tricks Unity into moving the affected areas so they don't overlap each other, although the thin area of the polygon can't overlap any other lit sprite or it'll appear very clearly.

If you have a play around, you should be able to get reasonable results, although depending on the angles you work with there are sometimes noticeable artifacts:
