[BUG] Wizard Breadcrumb visible on first step even though set to "Hidden"; `this.currentPanel` is `null`

Environment

Please provide as many details as you can:

• Hosting type
  • Form.io
  • Local deployment
    • Version: 4.11.0-rc.4
• Formio.js version: 4.10.5

Steps to Reproduce

1. Create a form
2. Set panel settings to display breadcrumb as hidden
3. Load form

Expected behavior

Breadcrumb should not be visible on the first page on first load.

Observed behavior

Breadcrumb is visible on initial load, but if you create a second page and navigate to the next page and then back to the first page you will see that the breadcrumb is no longer* visible.

This bug is likely related to tickets formio/formio.js#34 and formio/formio.js#2039

Suspected Bug

In Wizard.js line 154 the render code refers to this.currentPanel but during development of semi-related work I noticed that this.currentPanel is null during form initialization and there’s no render event emitted form formio on first render.
