Before the changes, when a message was posted (on Discuss or in the chat window), the composer was cleared directly as it didn't wait for the rpc response. If there was latency or a connection loss, the message disappeared from the composer but took time to appear in the content window or didn't appear at all and was lost. Now, the composer waits for the rpc response and then is cleared. Task #1957856 closes odoo/odoo#32422 Signed-off-by: Alexandre Kühn (aku) <aku@odoo.com>
