Subject: [PATCH] fix: guard against null msgInput before addEventListener in
 chat page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If msgInput element is somehow null, addEventListener throws and prevents
loadConvs() from being called — wrapping in null check makes it safe.
