closing a subtask as a duplicate of another task doesn't update parent task
Closed, DuplicatePublic



  1. create a parent task (A), a subtask (B), and an unrelated task (C)
  2. on task C, merge in duplicate task B

Expected result:

  • B is closed as dupe
  • I would've expected parent A to depend on C now

Actual result:

  • B is closed as dupe
  • but parent A only depends on B, not C

This is expected, we merge no information over when you close a task as a duplicate.

Or we already have a task on it. Either way.
