Previewing entry revisions fails

[ryanfoote]

Description

Attempting to preview a revision of an entry (specifically, not a draft) tosses a couple errors into the browser console:

Failed to load resource: the server responded with a status of 500 ()

Uncaught (in promise)

The XHR request is failing because Craft is tossing this error:

HTTP 400 – Bad Request – yii\web\BadRequestHttpException Post request required

Steps to reproduce

1. Open an entry
2. Choose a revision
3. Click the preview button at top-right
