MySQL 5.7 performance schema statement digest

The table performance_schema.events_statements_summary_by_digest is recording the same digest/digest_text for very different select statements that use views. Actually, the digest/digest_text of the view is being recorded.
It makes difficult to analize the performance in systems that use a lot of views, cause half the queries could be grouped under the same digest/digest_text.
Could it be a bug? Or it is the expected behavior?
