Accepted Chats Not Displaying in Salesforce Agent Console

Support Agents actively taking chats in the Service Console may notice that the chat window disappears from the agent console when accepting a chat.  When this occurs, see if the affected agent has other tabs/windows of different Salesforce apps open in their browser.  

If the agent has multiple tabs/windows of Salesforce open, the chat itself may focus on these other tabs/windows that cannot support chat functionality. This means that the agent will not see the chat window in the console, but the customer will still believe they are in an active chat as it is still connected and they are able to continue chatting. This happens intermittently.
