But they should be getting a query response for the A record for the same name, and then using that - assuming that they do actually query for the A record too?

Is the client actually broken because of the broken provisioning of the servers for cloud.huawei.com, or is the issue just the plague of log messages you're seeing?

(Aside: it is nevertheless a pity Huawei can't set up this delegation properly - it might just be an incompletely/improperly configured (maybe proxying?) set of load-balancers or something of that ilk).
