Passthrough markdown to issue body in new issue forms

I am converting my repository’s issue templates into issue forms, but there is one big problem: I want to pre-populate the issue body with some markdown that the maintainers will fill in once the issue is created. For example, I’d like the body to look something like:

# Question 1

Person's answer

# Question 2

Person's answer

# To Do

- [ ] Maintainer item 1
- [ ] Maintainer item 2
- [ ] Maintainer item 3

Right now, any markdown sections in Issue Forms will be removed from the issue body, but I want to keep them. Is there some way to pass-through raw markdown into the issue body?
