  <p>PREREQUISITE: User agent needs to have an enabled and capable spelling 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 "Txet sample" is yellow
    <li>if "Txet" has a desaturated lime green background
    <li>if " sample" has a very lite blue background and
    <li>if there is no red.
  </ul>

  <!--
    The bad spelling of Txet is intentional and part of this test.

    • 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)
