Ingo Bürk 9431ef16f6 Don't allow floating workspaces anymore.
This is essentially a revert of daf00a9 which introduced a mechanism
to float workspace containers by wrapping all children into a new
container and floating it.

This caused a bug and there's no good reason (anymore) to allow doing
this in the first place as we don't support floating nested containers.

fixes #2166
