Is there any way to have to tabcontrol take the size of the largest tab item (well, actually, the tabitem's content)? Since the tabcontrol has no specific size assigned it should autosize: it does that correctly, but when you switch tabs it automatically resizes itself to the height (and width) of the contents of the currently selected ...
