Cannot override legend style in outlinedtextfield

[AlexCppns]

I am trying to override the style with:

export const overrides = {
 MuiOutlinedInput: {
    notchedOutline: {
       "$legend":{
         transition: "none"
      },
      legend: {}
    }
  }
}

but it displays the changes in the wrong place in the css:

Anything I am doing wrong?

I managed to find the problem but now I am stuck because of this issue:
#13364

@AlexCppns I'm curious. Would #15140 have helped with the overrides?
