Added decodeEntities to eval-Array of the Checkout-Step-Selection.

Validation fails otherwise because of the backslashes in the option values. Closes #2193

Thanks for the PR! The option labels shouldn't be relevant for validation. Does the step name contain backslashes in your case? Did you create your own checkout steps?

[kollmeier]

It is not the label, which causes the problems. The value (or name) of the options are generated and contain the FQDN of the checkout-step (containing backslashes).

Wether I create own checkout steps or not leads to the same result: The checkout step select field of the MultiColumnWizard (as mentioned in #2193) doesn't validate, because \Isotope\CheckoutStep\PaymentMethod gets compared to \Isotope\CheckoutStep\PaymentMethod (for example)

After applying this submitted change, it works.
