Grunion form not displaying correctly in Text Widget

[hew]

To reproduce:

1. Paste this into a page:

   [contact-form] [contact-field label="Name" type="name" required="true" /] [contact-field label="Email" type="email" required="true" /] [/contact-form]
   

2. That should work fine. Now paste it into a Text Widget. You should now be seeing the following when viewing the widget on display:

   [contact-field label="Name" type="name" required="true" /] [contact-field label="Email" type="email" required="true" /] [contact-field label="Website" type="url" /] [contact-field label="Message" type="textarea" /] 
   

...with a submit button below it.

This is not a Grunion bug. A certain very helpful lead WP developer pointed out to me that it's core behavior (no shortcodes in widgets).
