   Hi, Airflow Web UI shows nothing on tree view for larger dags (more than 100 
tasks), although it's working fine for smaller dags. Anything that is needed to 
be configured in `airflow.cfg` to support larger dags in the UI?

   **Apache Airflow version**: 2.1.0 (Celery)
   
   **Environment**: 
   
   - **Cloud provider or hardware configuration**: `AWS EC2`
   - **OS** (e.g. from /etc/os-release): `Ubuntu 18.04`
   - **Kernel** (e.g. `uname -a`): `5.4.0-1045-aws`
   - **Install tools**: `pip`
   
   **What you expected to happen**:
   It is rendering correctly on `Airflow 1.10.13 (Sequential)`

   **How to reproduce it**:
   Create a sample dag with `>=` 100 tasks
   
   
   **Anything else we need to know**:
   The cli command for viewing dag tree is working correctly `airflow tasks 
list services_data_sync --tree`
