Why is ESLint not flagging the implicit any on this specific line:
// The variable `serializedResult` is of type `any`, which is permissible because the return value
// of `sendMessage(...)` is a `Promise<any>`. But why doesn't ESLint throw an error?
const serializedResult = await browser.runtime.sendMessage(serializedPacket);
Configuration files:
// Type declarations for functions are pulled from `index.d.ts`:
declare namespace browser.runtime
{
...
function sendMessage(message: any, options?: _SendMessageOptions): Promise<any>;
function sendMessage(extensionId: string, message: any, options?: _SendMessageOptions): Promise<any>;
...
}
// Configuration in .eslintrc.json

Could I be overlooking something? Is this setup correct?
