async keyword not properly highlighted in various places

[arch-mage]

I found async keyword is not properly highlighted places. Here some which I found.

export default async function fn() {} // Got 'jsExportContainer'
export async function fn() {} // Got 'jsExportContainer'

class Class {
  async method() {}  // Got 'jsClassMethodType'
  static staticMethod = async function() {} // Got 'jsClassValue'
}

const object = {
  async method1() { }, // Got 'jsObjectMethodType'
  method2: async function() { }, // Got 'jsObjectValue'
  method3: async () => {} // Got 'jsFuncCall'
}

I think async keyword there should be highlighted as jsAsyncKeyword.

@amadeus Voting for reopening. Bug still present for the most part. Copypasting OP's snippet gives me this: https://i.imgur.com/fifGcOp.png

Is this issue going to be fixed?
Adding jsAsyncKeyword into jsExpression cluster can solve this.
But I am not sure if it is the correct way to solve this problem...
