Source maps seems not to work at destructuring statements

source maps destructuring

Code

const { uid: modalId } = this.open({
  context: {
    onSubmit: () => {
      console.log('in onSubmit');
    },
  },
});

Expected behavior:
sources map should make it possible to add breakpoints at console.log('in onSubmit');
(works in vanilla js)

Actual behavior:
Breakpoints are not possible

#23346 would have changed this, wonder if that would affect it. @rbuckton

I don't know what is your status about this issue but as a full time typescript user, this issue mean that we just can't use destructuring in some cases.
