Tribute was already bound to BODY Wysiwyg editor?

Using Froala tribute js

Error:- Tribute.js:159 Tribute was already bound to BODY

When I am using froala fullPage.. And I have read the documentation as well and there is nowhere to mention this problem. The error is coming only when I am adding fullpage option and set it as true. This is not helping me to figure to any solution.
