TSLint complains about `> {` with generics and one-line.

Bug Report

• TSLint version: 5.4.3
• TypeScript version: 2.4.1
• Running TSLint via: (pick one) VSCode

TypeScript code being linted

// code snippet
export interface MyInterface<
  R extends string,
  D extends string,
  O extends string
> {
   /* ... */
}

with tslint.json configuration:

{
  "rules": {
    "one-line": [true,
      "check-open-brace"
    ]
  }
}

Actual behavior

TSLint complains about misplaced opening brace (one-line) on the > { line

Expected behavior

No complaint. This is essentially the same as the > ( in the following code, which doesn't trigger a TSLint error.

function test<
  R extends string,
  D extends string,
  O extends string
> (
  required: R,
  default: D,
  optional: O
) {
  /* ... */
}
