It's probably because Naver is a Korean website, with some English localization. In Korean, it's fine to split a word to a new line almost anywhere. I'm guessing it's using the same configuration even for English.

Expanding on the other answer, Koreans play Tetris with their letters, such that almost every "character" is a syllable-length block. eg. the food 떡볶이 tteok'bokk'i is written with three. You can just break a word anywhere because of how the script works. That's not the case with English.
