Hi,
not sure if it’s a known issue:
By selecting more than one element (ctrl + click), it is possible to move elements out of a pool, cf the following screenshot:

Thanks for reporting, I have created a bug for this one
Actually this is not a bug but a feature. You never really dropped the element outside the pool.
The better behavior is probably to get auto-expand working for pools (and other containers). See my comment on the issue.
