Hello,
I am sorry there's not a way to do that. The tabs themselves are wrapped in an outer div, and that div is automatically the height of the tallest child simply by its parent/child relationship of how the divs are wrapped.
The failure to automatically adjust height to content makes this extension unusable for responsive design. When adding content smaller than the tallest child, the responsive result is a lot of scrolling with what appears to be a blank screen in order to match up the tallest child.
