Yesterday, I don’t know why I decided to put ~~~~~ in a comment to see what happened. So what happened was that a strange bar appears.
If I add a word next to that the word disappears.
If I put the word in a line below, the word appears inside the bar but (< br / >) is added
I know it’s probably not a big deal since I don’t think many people use ~~~~~ for something, but I found it curious that this happened.
