I found one site not work even with 'HTML filter' option on
- The main problem is that the website cannot be displayed without jQuery.
- jQuery is embedded with crossorigin and integrity attributes.
- The HTML filter cannot remove these attributes because the string (HTML source code) has been split into two parts by filterResponseData() exactly at the point where jQuery is embedded.
- Collect data in a string array first and change it only just before writing it back.
