Child combinator (>) in :has sometimes vanishes when transpiling nested css

[malte-laukoetter]

When transpiling the following css using --supported:nesting=false the child combinator within the :has vanishes

.a :has(> .c) {
  .b & {
    background-color: green;
  }
}

result:

.b :is(.a :has(.c)) {
  background-color: green;
}

expected result:

.b :is(.a :has(>.c)) {
  background-color: green;
}
