Revision on https://github.com/odoo/odoo/commit/0d87b1ccea07b952d9079008cfa3cddaf1ccdbee
The commit above prevents opening a chat window when we do not have
access to messages of the conversation. This may happen when
receiving a notification from a document we do not have access
rights.
However, the changes in the code above has an unintended side-effect
of opening a chat window twice when clicking on a channel preview
from the systray messaging menu.
This happens because when clicking on a preview, it detaches the
thread and opens the chat window. Meanwhile, there is a RPC to
notify that the chat window is detached, and the new window state of
the channel is received on the longpolling. Two concurrent attempts
to open a chat window occur at the same.
It was working fine before the commit above, because the registering
of a newly open chat window was synchronous.
This is however no longer the case, because it fetches messages
beforehand: it has become a requirement to open a chat window. Since
the registering of a newly open chat window is now asynchronous,
it was fetching messages and opening the chat window twice.
This commit fixes the issue by aborting attempt to open a chat
window if it's currently opening a chat window, as this process may
take some time due to the `message_fetch` RPC.
