Standard shader - fade mode renders texture in wrong order

I found a possible solution to the problems.

Giving this result!

It is not perfect, but it works well enough for the fade effect.

The shader is based on the Unity Shader: Legacy Shaders/Transparent/Cutout/VertexLit which I have modified to fit my needs. I have removed a lot effects which I didn't need (Shininess, Spec Color, Emissive Color) and made it possible to make the tree transparent even if the texture is baked.

 Shader "Custom/Transparent and Cutout Shader" 
 {
     Properties 
     {
         _Color ("Main Color", Color) = (1,1,1,1)
         _MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}
         _Cutoff ("Alpha cutoff", Range(0,1)) = 0.5
     }
 
     SubShader {
     
         Tags {"Queue"="AlphaTest" "IgnoreProjector"="True" "RenderType"="TransparentCutout"}
         LOD 200
     
         // Non-lightmapped
         Pass 
         {
             Tags { "LightMode" = "Vertex" }
             Alphatest Greater [_Cutoff]
             AlphaToMask True
             ColorMask RGB
             Material {
                 Diffuse [_Color]
                 Ambient [_Color]
             }
             Lighting On
             SetTexture [_MainTex] {
                 Combine texture * primary DOUBLE, texture * primary 
             } 
         }

             }
