--parser typescript

Input:

interface Foo<
  loooooooooooooooooooooooooooooooooong,
  loooooooooooooooooooooooooooooooooong
> extends SomeType {
  foo: string;
}

Output:

interface Foo<
    loooooooooooooooooooooooooooooooooong,
    loooooooooooooooooooooooooooooooooong
  >
  extends SomeType {
  foo: string;
}

Expected behavior(2.0.5 output):

interface Foo<
  loooooooooooooooooooooooooooooooooong,
  loooooooooooooooooooooooooooooooooong
> extends SomeType {
  foo: string;
}
