Spreed: Recent chat history missing after switching conversations

[ChristophWurst]

Steps to reproduce

1. Have group conversation A
2. Switch to 1:1 conversation B
3. Get mobile notifications for A
4. Switch back to A (all via web)

Expected behaviour

See most recent messages from A.

Actual behaviour

Miss A history, but not only the new, unseen messages but also ones from the last few hours.

Browser

FF

Sending a message in there then reveals the missing history.

iOS client 6.1.0 is working well by the way. Whole chat is displayed.

Yep, Android is also fine. It's just happening on the web client.

Can not reproduce locally, so this seems to be an issue with the external signaling

Could it be related to very long chat history? Because I only see it in the bigger channels.

A look into the browser's debugging console reveals the following request URL:

https://cloud.nextcloud.com/ocs/v2.php/apps/spreed/api/v1/chat/....?lastKnownMessageId=18584&limit=100&lookIntoFuture=1&timeout=0

If you curl that with limit=-1 instead of limit=100, it shows everything. Otherwise curl gives the same output as we see in the web UI now.
