I dismissed it as "yet another part of the headers" and not as "part of the article".
I mean, to be fair, I was already aware it was removed from serde, but I'm pretty sure I didn't notice that box in the article the first time I read through it.
The top of the article looks like a screenshot of a chat, where someone said something, then some text and then the same person said something. I basically skipped that whole part to look for the article beginning, and when I didn't find the title, I skimmed back up.
The title is kind of hidden as it is right now, and the "notice" on the top doesn't look like a notice. Maybe try making it more different than other elements on the website, and put it below the article title rather than above?
I indeed missed the header, as other readers hear. I'd advise against using the characters' bubbles to provide important heads-up, as they're often used for additional insights or humorous opinion, and so can be easily missed by quick readers.
