It would be neat if you could natively block this annoying class of Iframe ads:
That specific one can be observed here: https://kissanime.com.ru/Anime/Detective-Conan.59465/Episode-121?id=12708 (if you set it to Hserver)
(also before someone complains, I do pay for crunchyroll, but ironically the pirate sites have better video playback...)
