This is just guesswork, I haven't checked the code: As far as I understand the way QoS is implemented in the kernel, a packet may only get out of the queue if the qdisc (in your case HTB) allows it to. If that's correct, the queue size should not matter, your problem is that HTB allows the 1:20 class to dequeue whilst 1:10 does not get a chance to do stuff. If you get a delay, then HTB is just too slow adjusting for the changed conditions. I haven't noticed such a problem myself though, since there is usually always traffic in my classes...
