Annotate with type from JSDocs generates a line break between generics instead of a comma

[VitorLuizC]

TypeScript Version: 3.9.2

Search Terms:
Annotate with type from JSDocs, JSDocs, Template (@template), multiple Template (@template) values, line breaks between generics

Expected behavior:
Generates a comma and a space between generics when click on "Annotate with type from JSDocs" and has multiple Template (@template) values.

/**
 * @typedef Either
 * @template L, R
 */

/**
 * @param {function(R): boolean} predicate
 * @param {function(R): L} onLeft
 * @returns {function(R): Either.<L, R>}
 * @template L, R
 */
function fromPredicate<L, R>(predicate: (arg0: R) => boolean, onLeft: (arg0: R) => L): (arg0: R) => Either<L,R> {}

Actual behavior:
Generates a line break between generics when click on "Annotate with type from JSDocs" and has multiple Template (@template) values.

/**
 * @typedef Either
 * @template L, R
 */

/**
 * @param {function(R): boolean} predicate
 * @param {function(R): L} onLeft
 * @returns {function(R): Either.<L, R>}
 * @template L, R
 */
function fromPredicate<L
R>(predicate: (arg0: R) => boolean, onLeft: (arg0: R) => L): (arg0: R) => Either<L,R> {}

Code

/**

 * @param {function(R): L} onLeft
 * @returns {function(R): Either.<L, R>}
 * @template L, R
 */
function fromPredicate(predicate, onLeft) {}

Output

"use strict";
