When embedding a piwik report the column description bubbles can are not fully visible.
Please see the demo for reference:

Thanks for the report. I'm able to reproduce it.
Guess we need to implement "smarter" tooltips for that, to make them able to decide where it's better to display them
Please point me in the right direction ... Maybe I can provide an improvement.
