I've created three tabs: two of them just have two single-line text input fields, while the third one has a big multi-line textarea.
Since that, the three tabs are of inequal height, and the Prev/Next buttons goes up and down the page when switching from/to the third tab.
How can I theme the tabs in order to make them all of equal height?
ps. I tagged this as a support request, but maybe it could be a feature request.
