Sugarcrm 7.9.3: Quote Line Items -CreateView- ReadOnly Not Working

I'm working on sugar 7.9.3, When trying to make a field in quote line item to readonly its not working. Following is the scenario.

I added product field status to show in quote line items. 

modules/Quotes/clients/base/views/record/record.php ( Worked in core file for testing)

array(
   'name' => 'product_bundle_items',
   'fields' => array(
               'name',
               'quote_id',
               'status',
   ),
),

modules/products/clients/base/views/quote-data-group-list/quote-data-group-list.php ( Worked in core file for testing)

array(
   'name' => 'status',
   'label' => 'LBL_STATUS',
   'readonly' => true,
),

As you can see the field is readonly but when u try to create a quote the field is editable.

CreateView


As the above record.php change not working, So i tried to make the field as readonly in modules/products/vardefs.php

'status' => array(
      'name' => 'status',
      'vname' => 'LBL_STATUS',
      'type' => 'enum',
      'options' => 'product_status_dom',
      'default' => '',
      'readonly' => true,
      'len' => 100,
      'audited' => true,
      'comment' => 'Product status (ex: Quoted, Ordered, Shipped)',
      'full_text_search' => array(
            'enabled' => true,
            'searchable' => false,
      ),
),

In product module DetailView the field become readonly and also in quote edit screen Quote Line Items its readonly, But when you create the field its not readonly.

Product Edit View, Its readonly

Tested with help of http://support.sugarcrm.com/Resources/Environments/Development_Environments/Vagrant_Development_Environment/ core sugar 7.9.3

The is not working in Create Quote screen. Seems sugar bug.
