Extension attribute ‘neighborhood’ not working when payment method is PayPal standard

I have added an extension attribute via

extension_attributes.xml

< ?xml version="1.0" ?>

    
        
        
    
    
        
        
    

It shows up when using other payment methods such as OpenPay, I can even see it when making a mock order (extension attribute is at the bottom):

Request Payload

Does anyone know if the process to read that attribute is any different when using PayPal as a payment method?
