Duplicate results with different domain capitalization

DA

Steps to reproduce:
Search for any globally unique headline from any popular website. Anything where you expect to find a specific and niche article on a specific site will do.

Expected behavior:
One search result per URL.

Actual Result:
Often, you get one result with the first letter of the domain capitalized; followed by another result from the exact same domain using different domain capitalization.

I believe the capitalized results are sources from Yandex. Results from the exact same URL should be merged.

Debug info:

Any browser and OS.

DA can you share the query and also any other query where this happens? we did not encounter this before

Here are some example searches:

In each example, you see two copies of the exact same URL that only differ in domain-capitalization. (I can confirm for sure that the two sites where these article headlines originate, ctrl.blog and vivaldi.com, have customized their SERP through the domain-capitalization tool in Yandex.Webmaster Central.)

DA Thanks, I was able to replicate the duplication issue. Looks like an easy fix.

DuckDuckGo used to have the same problem a couple of years back, if that is any consolation.
