wrong position for datapicker and element controls

To the color position issue refer to this one https://github.com/artf/grapesjs/issues/1533#issuecomment-432146597

@picozzo92 Are you able to create a minimal reproducible demo of this issue? I'm working on a big canvas refactoring that will probably fix all related issues, having a reproducible demo will help to understand that

I had same issue for colorpicker positioning and concluded that it's position is given related to screen / html tag (position: absolute , left: x px) , but if any parent element containing gjs-editor has position: relative , it will affect modal's position (if for example you have a sidebar on a page like I had).

Hope that this helps and can give some hints.
