chat doesn't update, and needs RC server reboot to reset it

Description:

often after a certain time of usage the chat doesn't publish or update new posted messages and they remain greyish
a browser update doesn't clear the issue with F5
so we need to reboot the RC server to get things working properly again
it's a render issue , because the message is saved , and with F5 it shows properly in the channels history

Steps to reproduce:

I noticed it happening more easily after a a week end of less activity

Actual behavior:

Additional context

Relevant logs:

No source files, tests, or entry points are named. Start by reproducing the stale chat-message rendering after a period of low activity, then inspect browser and server behavior to identify why saved messages remain grey until a server reboot; done means new messages render without restarting the server.
