In regards to the question In what order are creatures affected by the Sleep spell?, the asker had a sentence in the initial revision that stated that he was confused about the bugbear chief's Heart of Hruggek trait, which gives it advantage on saving throws against being put to sleep (along with other conditions) but checked the PHB and found that the sleep spell had no saving throw; the asker then went on to actually ask about the order in which the sleep spell affects creatures by HP.
I edited out the part about the bugbears as it is not entirely relevant to what's being asked, and almost feels like a second question.
Is this an accepted edit within the site's rules? Or should I refrain from doing this in the future?
