`channel.state.membership.notifications_muted` is inconsistent

[jhwheeler]

While the channel.muteStatus() function does return the correct mute status, the channel.state.membership.notifications_muted property is inconsistent; sometimes it is accurate, sometimes it is not. This changes in a seemingly random manner, but more often than not, it shows false even when the channel is true.

Is the notifications_muted property deprecated? It seems more intuitive for me to check the channel state object rather than calling a function to get a specific state property, especially how that is how the majority of other channel state properties work.
