I think you missed one:
Background behavior is ignored if the group is inside another group.
At least, your test case would seem to imply that...
I did a little test of my own:
group "Outer"
field
group "Inner"
button
With both groups set to act as backgrounds, the backgroundNames of this
card only reports "Outer" as a background. Apparently placing a
background inside another group hides the fact that it is set to act as
a background, even with its backgroundBehavior set to true.
