How to reproduce:

1. Navigate to Shop Settings > Stock Options
2. Enter html into the input "Mark product out of Stock" (e.g "
   !!!!")

You can see after saving that the value is not correctly displayed in the admin page or in cart

Feature:¶

I order to solve this problem we have to implement a new option inside SE4: Areas > Checkout > Shopping Cart
We have to create a new fieldset called "Out of stock label" with the options below:

• font-color
• font-style
• font-weight
• background group
• border group

Also we have to add a new css classes to the variables.scss of the theme in order to apply all those styles to the out of stock tag

• gx-out-of-stock-label-font-color
• gx-out-of-stock-label-font-style
• gx-out-of-stock-label-weight
• gx-out-of-stock-label-background-.........
• gx-out-of-stock-label-border-.........

The final result (example) that the user can achieve can be checked on the attached image.
