I was looking at this, but found it consistent across all versions of Maya,
so I'm not sure it qualifies as a bug. xD I even use it, to dynamically
alter the Channel Box based on the value of another attribute, like if a
node is disabled I can go ahead and hide other attributes that depend on
this value. But I wouldn't want this to be saved with the scene, since it's
temporary and cosmetic.
