AttributeData cannot be loaded when using a subdomain like https://backend.example.com/backend

[ray-magini]

Actual behaviour

Our Frontend is reachable under https://www.example.com and our backend under https://backend.example.com/backend.

When opening 'Store additional fields' within the plugin config to retrieve the possible attributes the plugin tries to reach the following URL: https://backend/AttributeData/list?raw=1&table=s_order_details_attributes&_dc=1586171977581&page=1&start=0&limit=25 This runs into an error as 'backend' is for sure not valid.

Issue

The store 'url' in Resources/config.xml is not working when using a subdomain which includes 'backend'

Potential solution

1. Make the url relative

   proxy: {
   type: 'ajax',
   url: '/backend/AttributeData/list?raw=1&table=s_order_details_attributes',
   reader: {
       type: 'json',
       root: 'data',
       totalProperty: 'total'
   }
   }

2. Or a different structure

   proxy: {
   type: 'ajax',
   url: window.location.protocol + '//' + window.location.hostname + '/backend/AttributeData/list?raw=1&table=s_order_details_attributes',
   reader: {
       type: 'json',
       root: 'data',
       totalProperty: 'total'
   }
   }

How can this fix be considered (eg. opening a pull request)?

Thanks, Dirk
