In the new issue view, create sub-task does not open dialog box

Issue Summary

The new "Issue detail view" does not open the dialog box when creating a sub-task

Steps to Reproduce

1. Set a required field in a Jira project
2. Navigate to the appropriate board
3. Select an issue and hit to create a sub-task, it will create as inline create issue
4. Create more than one sub-task

Expected Results

• Should open dialog box instead of the inline create issue

Actual Results

• The second sub-task isn't created and it shows an error message

Note: users may create one sub-task but it fails to create the second one.

Workaround

• Navigate to your profile(https://<instance_name>.atlassian.net/secure/ViewProfile.jspa) and disable "Issue detail view"; this is a per-user setting(each end user will need to make this change themselves)
• To create a subsequent subtask, use Create another option in the first subtask issue creation screen whenever feasible or the parent task needs to be refreshed.
