       "description": "This is the Issue Type Screen Scheme",
       "default-screen-scheme": "BugDefaultScreenScheme",
       "screens": [

               "name": "Bug -c/e- Screen",
               "tabs": [
                   {
                       "name": "General",
                       "fields": [
                           "issuetype"
                       ]
                   },
                   {
                       "name": "Dates",
                       "fields": [
                           "duedate"
                       ]
                   },
                   {
                       "name": "Effort",
                       "fields": [
                           "timetracking"
                       ]
                   }
               ]
           }
       ],
       "screen-schemes": [
           {
               "key": "BugDefaultScreenScheme",
               "name": "Screen Scheme - Bug",
               "default-screen": "BugDefaultScreen"
           }
       ]
   }

Notes

• When entering a value in one tab, the value is not even shared between the tabs.
• Tested in Jira versions 7.5.2 and 7.7.1
