Loading png file violates our CSP policy.
Is it possible to disable this loading in the settings?
Although it's not a security vulnerability, it still logs into console and is undesirable.

1. Open https://securingsincity.github.io/react-ace/
2. Open Dev Tools and select Networking tab with IMG filter
3. Observe that data:image/png is loaded
