TYPO3 Core

The "previous step" button in multi-step forms within the frontend does not work.

Example form definition:

identifier: test
type: Form
prototypeName: standard
renderables:
  -
    identifier: page-1
    type: Page
  -
    identifier: summarypage
    type: SummaryPage

A click on the "previous step" button does not redirect to the previous step. Instead, the form still stay on the current step.
