Manual refresh to remove "interrupted" connection status

Dear all,
We customized our own GUI for meet-jitsi based on old jitsi-meet version (but the lib-jitsi-meet is already up-to-date). I found that sometimes the jitsi-meet does not show up the cameras of participants, whose connection status is “interrupted”. And that situation just remains like that for quite long times until I refresh manually the page. Then the participants’connectionStatus changed (normally to “undefined”) and their cameras appear. Why does such situation happen? Where can I check / fix to make sure that the connectionStatus is updated frequently ?
Many thanks
