Default text in Visual mode in a Tab doesn't render

The Problem

Setting a behaviour with a default markup text does not render for fields in tabs (other than first)

Steps to Reproduce

• Create a behaviour that sets a default value for a field in the second tab

  getFieldById(IssueFieldConstants.DESCRIPTION).setFormValue("h2. This is a *test*")
  

• Open the create issue dialog and navigate to the second tab where the description field is
• In Text mode the value is there
• Toggle to Visual mode. The default value doesn't appear

The problem appears only when the field is in a tab except the first one.
