Bootstrap and Feedback widget not working together?

I'm having trouble getting the feedback widget working in mhy application. I used the bootstrap css as the basis for the styling and the setup of the index.html file. I found out that a clean project, generated from the app store downloading bootstrap, in combination with the feedback button is not working. I do see the differences between the index files, but I wasn't able to figure out how to keep the bootstrap styling and get the feedback button to work. Anybody? Thanks for reading. Update, as a response to Andries' comment: the bootstrap I mentioned is the Bootstrap for Mendix 1.0.1, not the editor. It's a theme rather than a widget. Just the index.html gives me problems in combination with the feedback widget, something in the way the layout is build up ...

Please note that you are mentioning Modeler version 4.7.2 while the app store states "Basic, bootstrap based, rich text editor for MX5 only."
