[WPK] Rabbit Hole Repository grid issues

In the preview pictures for the Wonderland Playroom Kit, it shows the Looking Glass Lounge neatly tucked under the Rabbit Hole Repository, but in the game, the default behavior doesn't allow this and there is a gap on the right-hand side.   If pressing the ALT key to bypass snapping objects to the grid, then it can be lined up properly when placed underneath.

Not sure if this is expected behavior.  I'm not a builder and just go with the basic controls, so had to look up the ALT key trick.
