CSS brightnesss filter blurs text
<p>Using <code>filter: brightness(x)</code> on an element leads to the text inside being blurred under Chrome and Firefox. Is this desired behavior? If not, can this be fixed? Here's a fiddle demonstrating the issue:</p>

<p><a href="https://jsfiddle.net/dye2n0xv/" rel="noreferrer">https://jsfiddle.net/dye2n0xv/</a></p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>button {
  border: none;
  background: linear-gradient(#53a423, #2f6c04);
  color: #fff;
  font-weight: bold;
  padding: 10px;
}

button:hover {
  filter: brightness(100%);
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;button&gt;
Some button label
&lt;/button&gt;</code></pre>
</div>
</div>
</p>

<p>Just hover the mouse over the button and pay attention to the text. Of course, the example with 100% is stupid, in my use-case I need something like 125%, but I wanted to make sure it's not the browser trying to display a whiter white than white, that's why I went with 100% which should theoretically not alter the element at all.</p>
