Some plugin features does not work as expected

[UlviShukurzade]

Dear @giterlizzi, first of all, thank you for great plugin.
In our institute's webpages we use bootswrapper actively. one of the most used (design wise) element is tab. as shown below.
this feature was working perfectly fine.

but after upgrading latest version of dokuwiki, this crushed. tabs are no longer displayed.
instead, all tab contents are displayed in sequential order. which is actually destroying our design in mind.

here is an example page.

Could please consider this issue? can you let me know if there is any way I fix it?
