This is pretty bizarre, but according to the MDN docs autocomplete has wide-spread support for TextArea element (given that the listed requirements are met):
https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/autocomplete
But it doesn't seem to work, at least not in either Chrome or FireFox.
This is an example of what doesn't work:
<html>
<body>
<form action="index.html" method="post">
<input type="first" name="input" id="a" autocomplete="on"><br> <!-- Works! -->
<textarea name="second" id="b" autocomplete="on"></textarea><br> <!-- Doesn't work!-->
<input class="submit" type="submit" value="Submit">
</form>
</body>
</html>
So this begs the question: has there been an actual regression in two major browsers, or are the MDN docs wrong? ... or am I missing something entirely different?
