Description
There is a defect in how membership system behaves when the public room creator leaves and tries to rejoin the it again.
Steps to reproduce:
- User creates a public group chat with any number of other invited users.
- Any number of users or at least one should accept the invitation.
- Creator changes image and/or group name
- Create leaves a room
- Someone invites the creator back to the room-> the creator can see the invitation
- Creator refreshes the page -> and the invitation is gone.
This problem happens with multiple sessions. Example: the creator might have like 4 other session in different browser. And for 3 of them this issue happens and the 1 is alright.
Note: In Element Web Client the invitation after refresh flashes for the fraction of a second and then it's gone.

Research direction
Start by reproducing the public-room flow: create and modify the room, leave it, get invited back, then refresh across multiple sessions. Trace how the Matrix SDK handles the invitation during refresh and compare the behavior seen in Element Web Client. Done means the creator's invitation remains visible after refresh in every session.
