Avoid incorrect legacy layout fallback inside NG-only display types.

NG-only display types (such as math and custom layout) will be treated
as monolithic if they occur inside a legacy multicol container, so we
don't have to let the ancestry trigger legacy layout fallback inside.
Besides, it would be bad, as we'd end up mixing NG and legacy objects
where this isn't allowed. It's only allowed at formatting context
boundaries, and not e.g. between a table section and a table row.
