I'm not doing anything other than applying/editing the extension Jason.
I'm afraid I'm not convinced by the "I'm not able to reproduce" line which, disappointingly, is becoming more frequent. The simple fact of the matter is that some WebAssist extensions do some very unusual things and are quite unreliable. I, invariably, end up on here having to find some workaround which is time consuming and frustrating.
I appreciate the resolution, but it would nice not to have to deal with weird code insertions. It's certainly nothing we're doing.
