[Bug]: Section Breaks don't work after a table of content

[Donnnno]

Describe the bug
First, this is a really nice editor!

I noticed that section breaks don't work after a table of content, see the screenshot for an example.
Not a huge dealbreaker, but I'm a huge fan of section breaks, it keeps a document organized :^)

Thanks!

Expected behavior
Create a section break after a table of contents
