How to avoid tall grass supporting dirt block?

[Wahazar]

I made simply mod, which add gravity to the block, it works fine except when block is sticked to the wall and there is tall grass underneath - this grass seems to support block above, which will not fall (until grass is broken) - is thre any way to override such glitch?

My json code:

[ 
 {
    "op": "add",
    "path": "/behaviors/-",
    "value": { "name": "UnstableFalling", properties: { fallSound: "effect/rockslide", fallSideways: false, dustIntensity : 0.25 } },
    "file": "blocktypes/soil/soil.json",
    "condition": { "when": "blockGravity", "isValue": "sandgravel" },
    "side": "Server"
  },
  {
    "op": "add",
    "path": "/attributes/allowUnstablePlacement",
    "value": true,
    "file": "blocktypes/soil/soil.json",
    "condition": { "when": "blockGravity", "isValue": "sandgravel" },
    "side": "Server"
  }
]

Seems this is rather kind of bug, (unstable block hoover on top of 3D grass) which is just not easily observed in case of high probability of falling sideways.
