There's no engine changes I can see in 9.0.4-rc-2 which could cause that 
so I suspect this will be due to a bug fix in the IDE - does it still 
happen if you Suspend Development Tools, or in a standalone?

Regardless of the cause, Monte's suggestion of using the 'relayer' 
command instead is what you should do - we added it to allow you to much 
more easily relayer controls around and in and out of groups *without* 
having to use an editing feature or try and figure out the somewhat 
opaque rules about what layer numbers actually mean when 
relayerGroupedControls is true.

Indeed, 'start editing group Foo' causes the engine to remove all cards 
and objects from a stack and store them somewhere self, create a new 
card and add the controls that were in the group as the new card's 
objects. Which is obviously a great deal more work than just moving a 
control somewhere else in the internal lists.

Warmest Regards,

Mark.
