the "shape custom rectangle" configuration of "list slicer" does not take effect

[Dajen-Z]

{
"name": "DajenTheme",
"visualStyles": {
"listSlicer": {
"*": {
"shapeCustomRectangle": [
{
"tileShape": "rectangle",
"rectangleRoundedCurve": 10,
"rectangleRoundedCurveCustomStyle": true,
"rectangleRoundedCurveLeftBottom": 10,
"rectangleRoundedCurveLeftTop": 10,
"rectangleRoundedCurveRightBottom": 10,
"rectangleRoundedCurveRightTop": 10,
"tabCutCornerSnipSizeTop": 10,
"tabCutCornerSnipSizeBottom": 10,
"tabCutCornerSnipSizeCustomStyle": true,
"tabCutCornerSnipSizeLeftBottom": 10,
"tabCutCornerSnipSizeLeftTop": 10,
"tabCutCornerSnipSizeRightBottom": 10,
"tabCutCornerSnipSizeRightTop": 10
}
]
}
}
}
}

No matter how I modify it, it has no effect
