I have a strange problem when a form is too deep for a page. Obviously, I want scrollbars so that the user can access the form.
But the width seems to be explicitly set too wide by the fitToForm algorithm:
Here is what it's like with the region expaned enough to fit the form's depth:
Then when I pull the splitter down a little:
You can see the width which must be set as an explicit CSS style on the element does not take the presence of the vertical scrollbar into account.
If I go into DOM Inspector and knock 20px off the width of the yui-ext-tabitembody element, it's fine, but move the splitter again, and the width jumps back up.
