The accessible name computation algorithm (accname) has a strict precedence order for computing an element's name. For an <input type="text"> that has aria-labelledby, aria-label, an associated <label>, a title, and a placeholder all present, which source wins and why?
<label for="f">Native label</label>
<input id="f" type="text"
aria-labelledby="a b" aria-label="aria label"
title="the title" placeholder="type here">
<span id="a">First</span><span id="b">Second</span>
