Selecting element with attribute containing [ or ] does not work since 1.4.4

[[email protected]…]

I have an input named data[User][openid] and want to select it using jQuery. The following code worked using jQuery 1.4.3 but does not work anymore using 1.4.4 (served from ​http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js)

<input name="data[User][openid]" />
<script>
// This should alert 1, but alert 0 in 1.4.4
alert($('input[name=data\\[User\\]\\[openid\\]]').length);
</script>
