Check out the URLs, there is an anchor in the URL (#). But that’s ignored. Manually browsing to the tab works indeed. But like I try to explain, you cannot directly link to a tab or anchor inside a tab other than the first tab. Please try to link to any of the tabs, it won’t open that tab when you open that link.
So my question is, how can I directly link to a tab (without instructing people to open the tab named “Zeit-Talks”). Furthermore, how can I directly link to an anchor which is inside one of the tabs? Because if I do, it only opens the first tab by default. If that anchor is in the first tab, then it works, if it’s not, then nothing happens.
Does this make it more clear?
