Hey Joe,
I found the problem with the accordion, I had a misconfiguration so it was not using the autoHeight:false, I had it like this:
{fx:{opacity:'toggle',duration:'fast',autoHeight:false}}
but that was incorrect because autoHeight is not part of the fx, it should be like this:
{fx:{opacity:'toggle',duration:'fast'},autoHeight:false}
I will fix this for the next release, but you could fix it immediately by specifying it on the ScriptLoader control in layout.master like this:
<portal:ScriptLoader id="ScriptLoader1" runat="server" JQueryAccordionNoHeightConfig="{fx:{opacity:'toggle',duration:'fast'},autoHeight:false}" />
