DemonChunk FLOORCLIP broken?

Riddle me this ZDoom forums.

If all actors derived from DemonChunk (the giblets of Hexen's green Chaos Serpent) have the FLOORCLIP flag, then why don't they actually clip into the water?

Code: Select allExpand view
ACTOR DemonChunk
  Radius 5
  Height 5

Is this a bug, or am I missing something?

Above screenshot is in software mode.

It clips into the water on hardware mode with varying depth depending on the 'adjust sprite clipping' setting. (maybe it's not actually floor clipping into the liquid and that's just the 'adjust sprite clipping' effect)

Now what is interesting, is I have a custom terrain defined with a deep 32 units of depth. This is used in black areas to hide the corpses of any flying enemies that may land in it.

Code: Select allExpand view
terrain darkvoid
   footclip      32

You would expect the demonchunk bits to be submerged completely, however they show the same clipping behaviour as regular water? (or is that just the 'adjust sprite clipping' setting taking effect? Really strange.

EDIT: pictures are better than words.

Both of these below were taken in hardware mode with 'adjust sprite clipping' set to 'Always' When set to never, the chunks clip into all floor surfaces regardless of the terrain.
