Element-R: when sending a first message in a room some device might be ignored because of recently tracked users not yet downloaded

[BillCarsonFr]

Steps to reproduce

1. Where are you starting? What can you see?

After a login with lazy loading, try to send a message quickly in a room. (in order to reproduce more easily you need the fix for lazy loading problem)

Outcome

What did you expect?

The message to be sent to all devices in the room

What happened instead?

Some users in the room have just been loaded (via a /member call), and marked as tracked. But the key/query has not yet be done (only done at the end of a sync when processing outgoing requests)

This is visible in the logs:

"The user has a pending /key/query request which did
not finish yet, some devices might be missing."

Occurence of this log in rageshakes: https://rageshake-search.tools.element.io/search_logs?log=some+devices+might+be+missing

EX is calling self.query_keys_for_untracked_users().await?; before sharing room keys.
