I have created a multi line text field and changed its Renderer to Wiki Style Renderer.
When I try to create the issue in the same tab and the Create Issue screen comes as a pop up in the same tab, the attachment button is VISIBLE, but when I try to create issue by right- clicking on the Create button and choosing option: Open in a new tab, the attachment button is INVISIBLE.
I am trying this with jira-administrator id and it has the permission to add attachment and system field Attachment is added in the screen.
Any help would be appreciated.
