Paginated containers are opaque to enclosing fragmentation contexts.

Paginated containers are opaque to enclosing fragmentation contexts.

Only multicol containers may be fragmented by enclosing fragmentation contexts.
Unlike multicol containers, containers with overflow:paged-x or paged-y cannot
create additional fragmentainer groups for each outer column that it lives in.

Added a basic test for multicol inside paged overflow, since it was missing,
just to make sure that this CL doesn't break anything.

Paginated containers are opaque to enclosing fragmentation contexts.

Only multicol containers may be fragmented by enclosing fragmentation contexts.
Unlike multicol containers, containers with overflow:paged-x or paged-y cannot
create additional fragmentainer groups for each outer column that it lives in.

Added a basic test for multicol inside paged overflow, since it was missing,
just to make sure that this CL doesn't break anything.
