bug: `hasMore` from `useChannelStateContext` doesn't reset

[mjcampagna]

Describe the bug

hasMore from useChannelStateContext doesn't reset when our channel is unmounted.

To Reproduce

When our channel has more than one page of messages, on first mount, hasMore is true, as you would expect. We then lazy load messages as we scroll, until there are no more, then hasMore is false.

Unmounting the channel component, and then remounting it, hasMore is still false, despite our now having only the first page of messages from the channel. At this point, we cannot use hasMore as a condition to lazyload the unloaded messages.

Expected behavior

hasMore should reflect the current state of the the channel. In our case, I would expect it to reset when the component is unmounted, then remounted.

Package version

• stream-chat-react: 12.14.0

Hello @mjcampagna , mounting and unmounting the React components does not reset the state of loaded channels. Could you please elaborate more on why would you like to load more pages if you arrived at the end before unmounting?

[mjcampagna]

When we remount the view that displays the channel messages, we only have the first page of messages again, and are unable to use the hasMore property in our lazy load logic to retrieve additional pages, because it’s stuck as false. That seems bugged to me.

My understanding is that the state is stored in the StreamClient, which is in our global context. Is there any way of reseting the channel state? I haven't found anything yet that would allow me to do that.
