When you isolate a group, you can set any part of selection inside this group as key object just by clicking it with Selection tool. This is great — I can align objects inside a group, yay.

But why I can't do the same inside of an isolated compound path?
Why can't I align parts of my compound path using another part of same path as a key object, as I can do inside groups?
Please, fix this.

See attached animation.
I try to align squares to the left side of the square hole (I made a guide to show the intention). But when I select them all and the hole only, mark it as a key and try to align — it all jumps to seemingly random spot, hardly matching my desired results.
