Minor bug - console errors

[charleswolfe]

I'm using angular-redcator 1.1.5 and redactor 10.2.5
Issue started when we switched to buble & browserify

Seems like it happens after we leave a page with redactor, and redactor can't be found anymore

TypeError: Cannot read property 'code' of undefined
at HTMLTextAreaElement.eval (eval at (redactor.min.js:12), :1:424)
