I downloaded the Tabs widget and increased the number of tabs massively.  My test page is here: <removed now that it works>

Note that only the first 3 tabs are active.  Note also that clicking on them causes weird spacing things to happen with tabs further on down.

So:  is it just not possible to have so many tabs on one page?

If it is, how do I stop this weird behavior?

Any and all help appreciated!
