**Reproduce on main:**
- Run a DAG
- Rename the DAG
- Wait for dag file processor to remove the deleted DAG and add the new one. (Old Dag should not appear on the home page anymore)
- Go to the Browse DAGRUN page.
- Click on a DagRun of the deleted DAG, as if you want to see the 'details/grid' of that old dag run
