Ignoring users working not properly

[Blager89]

Hello, I'm trying to implement an ignore function and ran into a bit of a problem

how to reproduce:
User A starts ignoring User B
User B sends several messages to User A
User A does not receive any messages from User B
then user A will unignore user B
User A received several messages sent by User B while User B was being ignored

sometimes I can get the last message, sometimes all messages, It depends on how quickly I unignore after the ignored user has sent a message

matrix js sdk version: "matrix-js-sdk": "^28.0.0"
Also attached 2 screens made in Element app

expected result: According to the documentation, the user should not receive any messages sent by him while ignoring the user

any thoughts on how to fix this?

I have same issue, however my theory is that's the way intended for "ignore" as stipulated by documentation:
After ignoring a user, the said user can still send messages to the Room. But you no longer get /sync events for those messages.

The messages are already in the room, they were always there. The server simply does not send them to you.
HOWEVER. After unignoring the user .. if you refresh page you will get/read ALL THOSE MESSAGES (none should be skipped).

What you need to do is a manual filtering. You need to make another "accountData" storage in which to store the ignore-unignore intervals/timestamps between those 2 users. Then filter the messages that fall in any of those interval so they are not shown on the chat, EVEN THOUGH they are sent by the server.
