Navigation Menu portlet won't list child of child pages

Issue

• While using any Navigation Menu portlet template different from the "List Menu" one (for example: Bar Minimally Styled), in a long page tree with multiple children pages, like:
  
  
  
  Only Welcome and Level1page will be shown:
  
  

Environment

• Liferay DXP 7.0+

Resolution

• The current issue has been handled in the form of a new feature through https://issues.liferay.com/browse/LPS-116120 and will appear in Liferay DXP 7.3
  
  
• Portal administrators and developers still interested to have the Navigation Menu portlet displaying the page tree-level after first child will have to implement an appropriate Freemarker template at their own discretion. Some sample resources with snippets (the result of individual contribution from Liferay community users), can be found here:
