Pick some question tagged and like this: Why didn't the basilisk bite in Chamber of Secrets destroy the Horcrux?

If you open it, the browser tab will be titled

harry potter - Why Didn't the Basilisk Bite in Chamber of Secrets Destroy the Horcrux?

Pick another question that is also tagged and like this one: How Did Harry Become a Horcrux?

Now the browser tab is titled

voldemort - How Did Harry Become a Horcrux?

What sort of algorithm was used to determine the browser tab's title prefix? Why are some questions prefixed with harry potter and others with voldemort and others with yet another different Harry Potter relatd tag?

I imagined that the most popular tag would be the one used for the prefix, and yet the one appears to prevail over the one in some cases.

If it is some sort of bug, it should be easy to fix by always prioritizing over .

    I'm not sure this matters in terms of the goals of all the stacks: to make the internet a better place. It might be a bug, probably someone will know. And Harry is not a Horcrux. ;) Sep 7, 2015 at 20:36
  • It's just the biggest (i.e. most questions) tag, unless that tag is already part of the title, which I guess is the reason for using voldemort in your second example. There's a canonical Meta Stack Exchange answer saying exactly that which I currently have a hard time finding (I think it's from Anna Lear).
