Thank you setting up a test page, it really made debugging easier. The problem turned out to be that your page is currently rendering in quirks mode, because of the invalid DOCTYPE:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
Please, replace with the correct one for HTML 4.01 Transitional:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
Or with XHTML 1.1:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
We will investigate if we can fix this problem, but switching to standards rendering should solve the problem.
