Although I have set the form variable modifier to protected, GUI component with not null Type Parameters are still saved
with private visibility.

Steps to reproduce :
* Create a new form 
* Select protedted as the form variable modifier
* Put a JTextField and a JLabel on form
* For Jlabel, enter a value into Code > Type parameters
* Save form and close it
* Reopen form and resize for example the JTextField
* When the form is saved, JLabel has private visibility instead of protected
