Dialog: No Scrollbars in IE in Quirksmode

This affects IE 7 and 8 as well. I have attached a very simple test html file that demonstrates the issue. I am going to try and fix this as I need it to work for a client project. I will submit a patch back to dev mailing list if I get it to work.

I have looked into this and this is related to how IE compute offsetHeight in quirks mode. When the dialog _size() method is called the nonContentHeight is computed using the jQuery.css method which for some reason does a jQuery.swap with a set of properties on the dialog element. One of the properties is display:"block". When that gets set on the element and the IE browser is not in strict mode then the elem.offsetHeight returns a very large value (in my case 478 instead of ~70 for strict mode). This link may help http://msdn.microsoft.com/en-us/library/ms534199(VS.85).aspx.

I don't have enough knowledge of css and the jQuery design architecture to understand the ramifications of possible changes so I am not going to try and fix this for quirks mode. I will just set my DOCTYPE to strict for a work around but I wanted to throw this out in case it helps one of the core developers get a jump on this issue.

For those, who cannot wait till this bug will be fixed (like me). Try to add this hack to the end of the _size() function:

if ($.browser.msie && $.browser.version < 7) {

this.element.css("width", this.uiDialog.width() - 28);

}

It's working for me in IE6 (I don't use quirks mode in IE7-8).

Unfortunately I don't know jQuery internals well enough to provide proper fix for this issue.

Problem is that the attempt to measure non-content height doesn't work in IE quirks mode because setting the content height to 0 is ignored. Fixed in r3838 by hiding content instead.
