Docs: API docs is all italic after castToSnapshot

[SpadarShut]

Bug report

• [x] I've checked documentation and searched for existing issues
• [x] I've made sure my project is based on the latest MST version
• [ ] Fork this code sandbox or another minimal reproduction.

Describe the expected behavior The API docs text is all rendered as italic after https://mobx-state-tree.js.org/API/#casttosnapshot castToSnapshot. I guess it's because there's <I> in type definition which is considered html and never closed.

Describe the observed behavior The text should not be italic, but normal.

Great find, @SpadarShut! Sorry that we've still got this open. I think we're going to rework the docs here at MST shortly, but I'll label this as a docs issue for now and close it when relevant.

Thanks!
