  • Don't know if it's the same for all browsers but on Firefox 62 it does... in the tab's name. (not optimal, but it's something)

Because that would costs space and it's not particularly useful. Contrary to the question body, which can contain markdown and many more kinds of formatting, there's only a very limited amount of formatting that can be applied to the title; AFAIK only MathJax (and some, but not all communities discourage the usage of MathJax in titles). Therefore, you can predict fairly easily how a title will look like and a preview is not necessary.

Note that comments, which support a lot more formatting than titles, don't have a preview either. And if you don't like for whatever reason how a title is rendered, it's fairly easy to change it; it's only a few dozen characters, not the entirety of a post body.

  • Absence of formatting doesn't mean you can predict fairly easily how a title will look like. I can't predict what the auto-"correction" will do.

  • I have posted a separate feature request concerning MathJax: Show a preview of the title when editing/asking - at least on the MathJax sites. (As you point out in your answer, it matters much less on sites where MathJax is not enabled.)
