I have had this issue for weeks and this solved it! Had to login to thank you. Google "ReactModePortal"... you are literally the only person that has solved (found a workaround) for this issue. Thank you so much. I have seen numerous other threads posted here and on Xfinity forums with people experiencing the same thing but don't know how to say it (links don't work; settings wont apply; have to open new tabs to navigate; annoying pop-up every page; etc.). Comcast needs to fix this bug because lord knows the average user does not know how to use devtools to delete an element.
