Small chat page scrollbar behaviour change

[terryleung00]

Currently, the chat page will have 3 separate scrollbar
The rightmost one will control the whole body causing some info being block

The fastest way to fix it is to force the height of the chat page from
flex h-screen w-full flex-row overflow-hidden
to
flex h-[calc(100vh-65px)] w-full flex-row overflow-hidden

but it requires a manual change in the future if the height of header is changed.
