Fix failing previews e2e test.

[Addison-Stavlo]

Description

Fixes a failing e2e by adding a step to wait for the input before trying to type into it.

This seems to fail inconsistently on different environments. It is failing sometimes in github, and seems to fail consistently locally for me. Since nothing happens between createNewPost and the type command, sometimes this happens too fast and it fails to not find the selector since it has not yet mounted.

How has this been tested?
