The handle-done-callback rule cannot handle TypeScript this parameter

[raymondfeng]

The issue can be reproduced with the following TypeScript code:

before(async function setupApplication(this: Mocha.Context) {
    this.timeout(6000);
}

Please note this parameter is used.

The handle-done-callback rule marks it as a violation incorrectly.

It's also interesting to note that the function is async.

Which parser are you using? I think this should be rather fixed in @typescript-eslint/parser.

[raymondfeng]

I use @typescript-eslint/parser. See https://github.com/strongloop/loopback-next/blob/renovate/major-typescript-eslint-monorepo/packages/eslint-config/eslintrc.js#L16

@lo1tuma Do you recommend we open an issue against @typescript-eslint/parser?

I run into the same problem. Is there any other solution than deactivating the rule for TypeScript files?
