   Hi @kaxil , please find the steps to reproduce the issue this PR is trying 
to solve.
   
   ## **Step-1: Sample DAG Runs**
   Using `example_bash_operator` as example, I have three DAG Runs, the first 
two are scheduled by the scheduler, and the 3rd one was manually triggered.

   ## **Step-2: Mark Failed for Task of Scheduled DAG Runs**
   I tried to click on the task `run_this_lat` of the 2nd DAG Run, which was 
scheduled by scheduler.

   Then I could see the confirmation page, in which there is a list of task 
instances whose state will be changed.

   Click on "Ok!", the state will be changed successfully.

   ## **Step-3: Mark Failed for Task of Manually-Triggered DAG Runs**
   
   Then click on the task `run_this_lat` of the 3rd DAG Run, which was 
**manually-triggered**.
