Missing / Incorrect Definition

navigator.connection is missing after updating Typescript from 4.5 to 5.3. I checked the other versions and it seems it got removed since version 4.8. However, I couldn't find this change in the breaking changes docs.

Sample Code

const c = navigator.connection;

Research direction
Find the dom.generated.d.ts file in the TypeScript repository and add the missing Connection type for navigator.connection. Look for existing Web API interfaces like Navigator and add the property.
