// promiseInterval - replacement for setInterval for promises, starts counting
// the interval only after a promise is done instead of immediately.
// - promiseCall is a function that returns a promise, it's called the first
// time after the first interval.
// - interval is the interval delay in ms.

export const promiseInterval = (promiseCall, interval) => {
  let stopped = false
  let timeout = null

  const func = () => {
    promiseCall().finally(() => {
      if (stopped) return
