ClientQuery addon channel_description channelvariable missing unless the channel is selected first

I’m trying to iterate over all channels and get their descriptions via the ClientQuery addon

Unfortunately it seems descriptions aren’t available to the addon unless the channel is first selected via the app

Is this behaviour expected, or is this a bug, and or user error?

I’m not entirely sure, but this looks like a ClientQuery limitation. It could be a bug CHANNEL_DESCRIPTION seems to only become available after the channel has been selected and the Client has loaded / cached the description.
