If the first decl ends by semi, it works fine

Input Code

I write a plugin to transform my code, it works with the leading comments

var s = `
/**
 * @test
 */
const a = {
  b: 42
}

/**
 * @test
 */
const c = 42
`
require('@babel/core').transform(s, { plugins: [
  function plugin(path) {
    return {
      visitor: {
        VariableDeclaration(path) { console.log(path.node.leadingComments, path.toString()) }
      }
    }
  }
]})
