I've noticed that Tabber, if there's no javascript, displays all tab contents. Tabber Neue seems to instead entirely become hidden, meaning the contents are no longer accessible. Are there plans to make TabberNeue degrade more gracefully?

That is very weird as TabberNeue should also display all tab contents. Do you have an example page with the issue?
I've noticed this happen in one case: the tabber seems to remove all of the other tabs and display all of the tab contents in the first tab when collapsible text is added in one tab.
