Registering multiple participants results in wrong event fee
When you allow for register multiple event participants, it makes you pay the first person's fee and input the payment info. However, the additional participants event fee is not selected till the 2nd page, so it does not calculate the total fee amount properly.
Reproduced at https://wpmaster.demo.civicrm.org/civicrm/?page=CiviCRM&q=civicrm%2Fevent%2Fregister&id=1&reset=1.
For now, we are limited to only allowing 1 registration at a time.
