   I can still reproduce on 2.5.0:
   
   If you have a paused DAG, and the DAG hasn't run for the current [data interval](https://airflow.apache.org/docs/apache-airflow/stable/dag-run.html#data-interval), manually triggering the DAG using the UI will simultaneously trigger two DAG runs:
   1. The manual run with a `run_id` similar to `manual__2023-01-11T15:27:32.643794+00:00`
   2. The scheduled run, because the DAG needs to become unpaused to schedule tasks for the manual run 
   
   If you can't reproduce it, I recommend confirming that there are no dagruns within the current data interval.
   
   I think the easiest change that would be generally good would be:
   
   If a DAG is paused and a dagrun will be scheduled if the DAG is unpaused, _and_ the DAG is attempted to be triggered by clicking the play button from the UI, the UI should show a warning indicating that a scheduled run will also be triggered.
