You are correct, the mentioned problem is still the same.
Although, as I mentioned, the W3C service is fetching the HTML content and the RadEditor
control is not related to the described images.
Note that they are requested from the HTML code provided by W3C and are set to validator.w3.org
domain, which is not hosted on the Telerik servers.
dialog is just using the W3C service and it is a simple iframe redirected to their site. Due to that we do not have the ability to control or modify the requested HTML content and I am unable to provide a possible approach to resolve this behavior.
