As in "I am still learning how to contribute on Drupal.org, so I wasn’t much sure about the issue queue life cycle. Me and my team are very actively working on all the Marinelli theme issues and trying to close all the issues which have been pending and unattended from long time.
So plan is to quickly analyze issue queue, push if the issue and the fix provided is genuine. In case somebody had any query, we are posting answers and closing the issue.
Thanks for all the help. All the feedback will be appreciated and good learning lesson for me."

The CSS provided resolves the issue and is a useful addition, also in accordance with minimal development and maintenance in D7 branch.
