Stef,

   If I understand correctly, all filters related to the HTB leaf
classes should be attached to the HTB qdisc.

   It would have been nice to attach filters to parent HTB classes...

No, I was only speaking about the default class.  You have a filter that put
some packets in 4:200.  The rest of the traffic goes to the default class
4:100.  But the packets are immediatly dequeued in class 4:100 so the filters
attached to 4:100 are never checked.  You can simulate a default class if you
add a u32 filter with src 0/0.
The default class is for unclassified packets.
