For an existing View in a Preview, ensure we pull the same ActionCollection

[scottbell]

Closes #7158

Describe your changes:

In Preview mode, we weren't pulling the same cached copy of the ActionsCollection, and thus weren't picking up any state changes from the View.

All Submissions:

• Have you followed the guidelines in our Contributing document?
• Have you checked to ensure there aren't other open Pull Requests for the same update/change?
