Custom Checkout Step and Shipping Step are Highlighted and Combined upon Checkout page load

[natebatty]

Preconditions

1. Magento 2.1
2. PHP 7

Steps to reproduce

1. Create a custom checkout step. Set the step to appear first.
2. Start the checkout process
3. Both my custom step and the shipping step are displaying and highlighted
4. Upon using the next buttons the steps show up in their own section

Expected result

1. Shipping step should be hidden since it is now step 2

Actual result

1. Both my custom step and the shipping step are displaying and highlighted

I can confirm the same behavior. I also created a custom checkout step (sortOrder: 0 in the xml, sortOrder:5 in js) so that it would appear before the shipping step. When you first visit the checkout, it will show both steps highlighted on the top bar. Additionally, the content for both steps will both be shown until you click the next button. It will run the validator for my custom step, then move to the shipping step. From here, I can move back to my custom step and it will display only my custom step. Not surprisingly, I can also visit "http://localhost/checkout/#mycustomstep", and it will properly display my step on it's own.

Attached is a zip of my module, which may be helpful in debugging this issue.

There may be a workaround described in this issue report, but I'm still trying to understand what is said... #8875
