Steps to reproduce the problem:
function throwError() {
  return new Promise(resolve => {
    setTimeout(resolve, 10)
  }).then(() => {throw new Error('blah')})
}

function thisWorks() { return throwError() }
async function thisDoesnt() { await throwError() } 

thisWorks()
thisDoesnt()

Run this with "Pause on exceptions" ticked, but not "Pause on caught exceptions"

What is the expected behavior?
It should break on the error twice, and print both to the console as "uncaught (in promise)".

What went wrong?
It only breaks on the first one. Both errors do get written to the console correctly though.

Did this work before? N/A

It breaks on both errors if you tick "break on caught exceptions".
