Steps to reproduce:

  1. In the Admin, go to Stores > Settings > Configuration > Sales > Sales Emails > General Settings and set Asynchronous sending to Enable.
  2. Arrange for two sales email cron workers to process the pending order confirmation concurrently.
  3. Place a new storefront order using a valid customer email address and complete checkout.
