Problem with tabs in IE6 after upgrade from 1.6rc6 to 1.7

Problem with tabs in IE6 after upgrade from 1.6rc6 to 1.7


Hello,
I have a page with three basic jQuery UI tabs, each of which contains
an iframe. The src of the iframe is set when each tab is first
selected, however if I hard code the src's the issue is still present.
In Firefox 3 and IE7 the tabs load fine and everything works as it did
before the 1.7 upgrade. In IE6, the tabs are displayed but the none of
the iframes show up unless I insert one or more characters before the
iframe tag. Here's an example of the div containing the frame:
The contents of this iframe will NOT display in IE6:
<div id="tabOne" class="iframeTab">
    <iframe class="contentFrame" frameborder="0" src="http://
www.google.com">Your browser does not support frames.</iframe>
</div>
And this one will:
<div id="tabOne" class="iframeTab">
    a
    <iframe class="contentFrame" frameborder="0" src="http://
www.google.com">Your browser does not support frames.</iframe>
</div>
I have since reverted to jQuery UI 1.6rc6 and everything is working
fine again. Has anyone else experienced this issue or know what might
be causing it?
