Hey guys, I work as a developer at Wix.com. We are suffering from the same issue and many users are complainig. When embedding the iFrame into an HTML file, if the file is too long or has a very long query string parameter, the browser tab hangs with 100% CPU usage.
Here is a reproducible link: http://ponya.co/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.html
Any estimation on a fix?
