Is this behavior normal for Yandex?

Question

MySQL

I saw on the IT resource a banner "virtual walks through Chernobyl", a link to Yandex. Passed, there is a big button like "start tour". When I press it, the following warning appears:

If you press cancel, the tour does not open. There is no interest in putting these things on yourself. Is this normal for Yandex?

Answer 1

(*Despite the fact that the search code on both sites is the same, since the same WordPress theme is used)

This is never a guarantee that there is the same code.
The search works this way because it clumsily selects the data, look at what is in the database itself, there may be an error there

Answer 2

I had this on the site xeor-pw.info , the case really turned out to be in the database.
