Consider this structure:

card
     button 1
     group A
         group AA
             button 1AA
         button 1A
     background B  (group with background behavior checked)
         button 1B

A little mouseUp handler on each object that logs and passes shows this:

card -- background B -- stack
button 1 -- card -- background B -- stack
button 1AA -- group AA -- group A -- card -- stack
button 1A -- group A -- card -- stack
button 1B -- background B -- card -- stack

(No handlers change scripts to add or delete handlers.)

Both the card and button 1 see the background.  Button 1B sees the 
background in a different order.

But, I expected this:

button 1AA -- group AA -- group A -- card -- background B -- stack
button 1A -- group A -- card -- background B -- stack
