Bug in the Pikabu app (Android).

There is a very popular Russian entertainment service that resembles Reddit. The service is called Pikabu, with the app of the same name in the Play Market. When entering text in comments, there is a bug when entering text in Russian: in a new paragraph (after pressing Enter) the second word is always obtained with the first letter of the word doubled ("Иван Иванов" will replace "Иван Ииванов"). The bug is very old.
