 I'm building a site in (a child theme of) Twenty Nineteen. In the top
 menu, each instance of a menu item that has a child item is returning one
 error in the WAVE accessibility tool. The reported error is "empty button"
 and below is the explanation:

 What It Means
 A button is empty or has no value text.
 Why It Matters
 When navigating to a button, descriptive text must be presented to screen
 reader users to indicate the function of the button.
 How to Fix It
 Place text content within the <button> element or give the <input> element
 a value attribute.
 The Algorithm... in English
 A <button> element is present that contains no text content (or
 alternative text), or an <input type="submit">, <input type="button">, or
 <input type="reset"> has an empty or missing value attribute.
 Standards and Guidelines
 1.1.1 Non-text Content (Level A)
 2.4.4 Link Purpose (In Context) (Level A)

 This is the HTML that is returning the alleged error:
 <button class="menu-item-link-return" tabindex="-1"><svg class="svg-icon"
 width="24" height="24" aria-hidden="true" role="img" focusable="false"
 viewBox="0 0 24 24" version="1.1" xmlns="http://www.w3.org/2000/svg"
 xmlns:xlink="http://www.w3.org/1999/xlink"><path d="M15.41 7.41L14 6l-6 6
 6 6 1.41-1.41L10.83 12z"></path><path d="M0 0h24v24H0z"
 fill="none"></path></svg>About us</button>
