<p>PREREQUISITE: User agent needs to have an enabled and capable grammar error module. If it does not, then this test does not apply to such user agent.
<p>Test passes
<ul>
<li>if each glyph of the sentence is yellow
<li>if "thing" has a desaturated lime green background
<li>if the other words have a very lite blue background and
<li>if there is no red.
</ul>
<!--
The grammar mistakes in the text below are intentional and part of this test.
https://html.spec.whatwg.org/multipage/interaction.html#spelling-and-grammar-checking
• contenteditable makes the text “checkable for the purposes of [spelling and grammar checking]”
• spellcheck tries to enable spelling and grammar checking (subject to user preferences)
• lang tries to guide the UA towards checking the text in English (but the UA may ignore this)
-->
<div id="test" class="highlight_reftest" contenteditable="true" spellcheck="true" lang="en">Many thing can happen.</div>

const test = document.querySelector("#test");
