Board posts: Creating a new post requires leaving the page

[Riscky]

Expected behaviour

There is a button that allows the creation of a new post

Actual behavior

When a post is clicked, it shows up in the edit pane. There is no way to return to the empty edit pane except for leaving the posts page and returning to it.

Steps to reproduce

• admin
