The PR most likely needs to run full matrix of tests because it modifies parts of the core of Airflow. However, committers might decide to merge it quickly and take the risk. If they don't merge it quickly - please rebase it to the latest main at your convenience, or amend the last commit of the PR, and push it with --force-with-lease. |

In the
task_run, it has to dispose the ORM then configure orm, otherwise, the existing db connection won't be closed. When there are lots of running tasks, the DB is likely to get connection error.Test:
