own_capabilities extraData missing after update

I'm watching channel.extraDataStream and printing its content and it looks like after calling channel.updateName I get a new value in the stream (as expected) but without own-capabilities. Is this expected behaviour?

And that is the state in which the channel is then cached and from now on when checking permissions there are none.

@Brazol can you share a small snippet using which we can reproduce this? Thanks

I'm using hooks so it will be easiest for me to share it that way, but basicaly I just listen to extraData:
final extraData = useStream(channel.extraDataStream, initialData: channel.extraData);

and when I get new data I print it:
useEffect(() { print(extraData.data); }, [extraData.data]);

and initially I get correct json with own_capabilities array of permissions but after calling
channel.updateName
there is no own_capabilities (extraData only contains new name)

@Brazol Thanks, I was able to reproduce the issue. We will release a fix soon.

thanks, @xsahil03x, now that I upgraded to 4.0.0-beta I also notice it sometimes that ownCapabilietes property is empty after update to the channel. Is it connected and will your fix also fix 4.0.0-beta?

Edit: also membersStream is returning empty data after channel.updateName is called
