Bug report: DOM manipulation causes constant and disruptive spam in browser console



Firstly: This is mainly an issue for web developer.



The JavaScript console gets spammed the following:

Uncaught TypeError: Cannot read property 'indexOf' of undefined
    at HTMLBodyElement.<anonymous> (content.js:2)
    at HTMLBodyElement.dispatch (jquery.js:104)
    at HTMLBodyElement.k.handle (jquery.js:98)


Webpack Hotmodule Reload or another substantial DOM manipulation event.



Developer sanity is degraded.



Disable F-Secure KEY when developing in the browser.

    Hi Muta,


    Does it happen on some specific website only?

    This happens when developing websites. Have not encountered this on production sites, only on development sites with webpack or equivalent hot module reloading features enabled.


    I think this is an issue that happens because of the full DOM tree reload after the manipulation on Angular Universal. I haven't tried it on React or jQuery manipulations yet.
