// TODO: Contribute these helpers back upstream once we are on the latest version of
// ember-power-select (4.x)
//
// selectOpen and selectOpenChoose splits the existing selectChoose helper into two pieces
// - selectOpen: open the select (await settled)
// - selectOpenChoose: choose an option (await settled)
// Since the composite helper has two `await setted`s in it, the log changing tests can't use
// them. These tests require a run.later(run, run.cancelTimers, ms) to be inserted between
// these two moments. Doing it before opening means hanging on open not on select. Doing it
// after means hanging after the select has occurred (too late).
