Specifically this part:
body {
font-family: Verdana, Arial, Helvetica, sans-serif;
font-size: .8125em; /* 13px (see note above) */
text-align: center;
margin: 0px auto 0px auto;
padding: 0px;
background-color: #FFFFFF;
position: relative;
z-index: 0;
overflow: scroll;
}
The highlighted declaration is new. Anyone that is comfortable setting up a user style sheet or is using a browser add-on to do user styles can fix the issue by adding the following:
body {
overflow:visible !important;
}
Tested in Opera (since it is so easy to do user style sheets). I probably will do some testing in other browsers shortly, but I doubt that is even necessary.
