 @azaozz is correct. I looked more closely inside one of the affected JS
 files and found "WiredMinds eMetrics tracking with Enterprise Edition
 V5.4". Google search returns your host Telus as one host that inserts
 pixel tracking code willy-nilly into files, including the middle of JS
 files.

 code-on-our-web-pages

 Solution that worked for me was logging into ATT hosting, finding
 Analytics, poking around till I found Web Analytics | Advanced | Manage
 Pixel Code. Set to off, clear cache, hard refresh on admin / editor and
 it's fixed.
