Fix `l.content()` not using `louter.ref()` correctly

Currently it just sets metadata, but it never connects to louters `ref()`

Look for the `l.content()` method and the `louter.ref()` function in the codebase. The issue indicates that `l.content()` sets metadata but does not properly connect to `louter.ref()`. Start by examining how `ref()` is used elsewhere and trace the flow to understand the missing connection. Check for existing tests related to content or router references to see the expected behavior.
