A work request's dynamic data is not shown in the Internals tab

If you look at the "Internals" tab of a work request (example), then you will always see "Dynamic data: Work request is not configured":

And yet I can confirm from the database that those work requests have a non-NULL dynamic_task_data field. It might be related to #1012 (closed) and the fact that configured_task_data is NULL... Both are expected to be computed at the same time, so it would not surprise me that they use the same test to decide whether it's configured or not.
