There is an “InvalidArgument”error when we are using AccordionPane for some scenarios. It looks like the layout function is causing the problem where the following calculation results a negative value for InternetExplorer (IE). However for other browsers it works fine.

“this._verticalSpace = (mySize.h - totalCollapsedHeight);”

Why this is returning a negative value for IE?

I have attached a sample HTML pages for testing this. Just try to load the Sample_index.html. You cant see the right hand side AccordionPane is not loading.
