As a user, I want to be able to browse the website and keep the side menu panes consistent with my browsing behavior. For example, if I open a technique from the Defense Evasion tactic and then click on the subtechnique link, it opens the link with the side navigation menu visible with the Execution tactic pane instead of Defense Evasion.

To prevent this behavior, we should keep states of the technique/subtechnique browsing so that we can open the correct pane. Such capabilities must added to the navigation.js script.
