This is a limitation from floats. But wrapping code within a listings
environment is, IMO, the right thing to do, otherwise, cross-references
will not work.

A hack around this would be to drop the environment when source code
exceeds 30 lines, but that's cheesy for sure.

Or, maybe, drop the environment when there's only the label, but only
when there is no cross-reference pointing to the src-block within the
whole parse-tree.
