+def _filter_queryset_safely(queryset, **query):
+    """
+    Safely filter a queryset, even if it has been sliced.
+    When a queryset is sliced (e.g., queryset[:3]), Django sets
+    query.is_sliced = True which prevents further filtering. This function
+    works around that limitation by temporarily removing slice limits,
+    applying the filter, and then re-applying the slice limits.
+    Args:
+        queryset: The queryset to filter (may be sliced)
+        **query: The filter arguments to apply
+    Returns:
+        The filtered queryset with original slice limits preserved
