Issue with focusSubtabById & alternative approach

We had used the onFocusSubtab function in an VF page with standard controller( overwritten for a standard object view action).

When we use the onFocusSubtab for doing some business logic it woks only with latest tab opened in the service console.

Issue: when a tab is closed and open other record from the same object, onFocusSubtab stopped working. Not only it stopped working, it also breaks service console.
Ex..

• Other tabs will start behaving abnormally, like content of other tabs will display for some other tab.
• In one case, it splits screen in half and disturbs whole service console and tabs.

Resolution: We have to use alternative approach to deal with the onFocusSubtab 

Solution: In the same place use an addEventListener for CloseTab event
