Comment:

 @CarolKn and @knutsp are right. This is not an issue in WordPress. It's
 not even an issue exactly with the web hosting companies, it's some
 software they are using turns out to be buggy.

 @smartabhay27 imagine the post office opening your letters, cutting them
 in half and sticking a paragraph written in... Latin in the middle. Would
 you blame the sender of the letters then? :)

 I have no idea why somebody would append a HTML string in the middle of a
 JavaScript file. This is bound to fail in almost all cases. Perhaps they
 had a good reason for doing it, but... It breaks sites.

 I also don't know why this started happening now. The file being affected
 is not from WordPress itself. It comes from the TinyMCE open source
 project and WP doesn't modify it in any way. My guess is that it started
 matching some sort of pattern so the pixel inserting software decided it's
 OK to add HTML tags there. I'd like to repeat that inserting HTML strings
 in JS files seems like a really bad idea in the first place, and that
 software should be fixed.
