Creating New Individual via quick add block fails if after adding you try to add a phone number
Drupal 7.59 CiviCRM 5.3.1
I was able to replicate on https://dmaster.demo.civicrm.org/ demo site. When contact is created through add individual contact block and at least one of the custom field is required, on the full individual create form if phone field is populated and form is submitted, it gives error saying "One Phone should be marked as primary".
There is already a JIRA issue created for this bug but no resolution yet. Jira issue: https://issues.civicrm.org/jira/browse/CRM-5207
Thanks!
