### Apache Airflow version

2.1.2

### What happened

Task duration view for triggered dags shows all dag runs instead of n last. Changing the number of runs in the `Runs` drop-down menu doesn't change the view. Additionally the chart loads slowly, it show all dag runs.

### What you expected to happen

The number of shown dag runs is 25 (like for scheduled dags), and the last runs are shown. The number of runs button should allow to increase / decrease the number of shown dag runs (respectively the task times of the dag runs).

### How to reproduce

Trigger a dag multiple (> 25) times. Look at the "Task Duration" chart.
