Hi Supun,
I just noticed a bug. When the phpMyAdmin configuration storage is active, the last column on which you sorted a table is remembered. The next time you browse this table, it's sorted on the same column, and you see a small triangle next to the column name.
The small triangle no longer appears when this sorting on remembered column is done (tested on sakila.actor).
git bisect tells me that the problem started with
https://github.com/phpmyadmin/phpmyadmin/commit/ebef06fa0df162a5852efab68fab...
