I ate a salad that had raw onions cut with a fleishig knife. Do I need to wait six hours? 👀

I ate a salad that had raw onions, and the  onions were cut with a fleishig knife. Now,   the rule is that we consider these onions to  be fleishig. Do I have to wait six hours after   eating these onions (before eating dairy)? the  answer is that you do not have to wait six hours,   and the reason is because there's two primary  reasons why we wait six hours when we eat meat.   One is because of meat getting stuck between the  teeth, Because then when I continue to eat cheese   afterwards or anything dairy, it's like I'm eating  the meat and cheese together Because there's   still meat stuck between my teeth. And the other  reason is because meat has a very strong taste,   and even hours later, you still feel the  taste of the meat in your mouth, therefore,   it feels like you're eating the meat and cheese  together. So for those reasons, you wait. Some   people wait one hour, three hours, six hours, five  and a half hours, whatever the amount is that you   wait. Neither of these reasons apply to an onion.  An onion in this context is what we would refer to   as a tavshil shel basar, meaning it's a food that  was cooked together with meat. In this case, it   wasn't cooked, it was cut with a knife, but it has  the same status as though it was cooked with meat,   and therefore the onion is fleishig, just like  a potato that was cooked with meat is considered   fleishig. So after I eat a potato that was in my  cholent, I wait six hours. It's only a minhag that   we wait six hours in this case, but the poskim say  that this minhag does not apply to the onion that   was cut with the fleishig knife since it was never  even in direct contact with the meat. It only came   in contact with the meat through the knife, so  there's no minhag in this case to even wait six   hours. It's considered too far removed even for  the minhag. And therefore, if a person eats an   onion, even though halachically it's considered  fleishig, you do not have to wait six hours.
