Create issue with field required does not save the changes

Issue Summary

Creating an issue from the plan view does not save the changes on other required fields such as summary and epic name.

This is reproducible on Data Center: (yes)

Steps to Reproduce

1. Create a new Select List custom field.
2. Associate the Select List custom field to the create issue screen.
3. Go to the Field Configuration and set Select List to required.
4. Go to the Plan view and create the issue inside the plan.
5. Click 'review changes' and proceed with the 'save selected changes in Jira'.
6. You get prompted a pop-up box to fill in the required field:
   
7. Change the Summary to "any summary"
8. Change the Epic Name to "any epic name"
9. Update the Select List field value to "any value" and save the changes.
10. Open the issue screen and notice Summary and Epic Name still shows the same value without any changes:
    

Expected Results

Users should allow changing the issue summary and epic name when they modify the value in the pop-up box.

Actual Results

Issue summary and epic name value remain the same even though Jira allow users to change the value in the pop-up box.

Workaround

Open the newly created issue from the plan and edit the necessary field value.

Notes

The workaround was recommended in JPOSERVER-2794 and seems to be not saving the changes on other required fields.
