"https://mifosforge.jira.com/browse/MIFOSX-1685 : Sub-section or tabs - during "browser back" navigation - the UI should retain the tab from which user navigated away. For Example, user is currently on "Repayment Schedule" tab for a loan account, User clicks on "Client Name" to go to the Client Summary. User clicks on browser's back button. The user should come back to "Repayment Schedule" tab instead of "Account Detail" tab."
