Whenever I try to open a large configurable product with over 4000 simple products I get the following error:
Warning: DOMDocumentFragment::appendXML(): Entity: line 1: parser error : internal error: Huge input lookup in /vendor/magento/framework/View/TemplateEngine/Xhtml/Template.php on line 60
I found this issuetracking, but there the problem is about the order grid. https://github.com/magento/magento2/issues/8084
Any idea how to solve this? I'm on version 2.2.1 because of a Shipping module for the Netherlands.
