Example:
const decl = postcss.decl({ prop: 'foo', value: 'bar' });
const atRule = postcss.atRule({
name: 'foo',
nodes: [decl],
});
const comment = postcss.comment({ text: 'hello' });
// TypeError: Cannot read properties of undefined (reading 'insertBefore')
decl.before(comment);
Is this intended? I'd expect the child nodes to be updated, but instead they get cloned, and therefore the original instance is not updated.
