Layout Group ID is not published while using "Link to Page" field inside the web content

Issue

• Steps to reproduce
  1. Create two public pages First and Second in the default Guest site.
  2. Create a custom structure and template "Link to Page" by referring the attachments.
  3. Create a new web content of structure type "Link to Page" with its content.
  4. Now drop this content on First page of the site.
  5. Setup a local live publication for the site and publish the structure, template, content and the page.
  6. Now check the First page on live site. Upon inspection you will find that the group Id is missing.
  7. The issue is that the link to page field is stored as "LAYOUT_ID@LAYOUT_TYPE@LAYOUT_GROUP_ID" in database but when we publish a web content containing link to page field on live site the layout group id goes missing and what is stored is "LAYOUT_ID@LAYOUT_TYPE".
  
  Expected Behavior: LIVE_LAYOUT_GROUP_ID should be appended to LAYOUT_TYPE field.
  Actual Behavior: LIVE_LAYOUT_GROUP_ID is not appended to LAYOUT_TYPE field.
