Steps to Reproduce

1. In a next-gen/team-managed project, Create a task and subtask and make them belong to the same sprint
2. In the Jira issue search screen, perform search by the following:

   project = <project key> AND Sprint = <sprint id>
   

Expected Results

The task and the subtask shows up in the search result

Actual Results

• Only the task shows up in the search result
• For search results where the Sprint is EMPTY clause is used, the Subtask issue types (whose parents belong to a sprint) are incorrectly listed in the results despite belonging to a sprint. 

Workaround

There are no workarounds at the moment

Note

This is affecting the following APIs as well

• /rest/api/2/search (passing "Sprint=<id>" as argument)
• /rest/agile/1.0/sprint/
