Widget - Table content partiallly disappears when clicking "Display a table with more metrics"

Really strange issue but while on the dashboard view when you click on “Display a table with more metrics” icon and close the popup, only first column is visible on the widget. And similarly on Visitor Browser widget on the dashboard, when you click the same button, the footer draw icon appears on top of the text (PWK_ERR_2.png). Screenshots attached.

Steps to replicate:

  1. Go to http://demo.piwik.org
  2. On the Keywords/Referrer Websites Widget, click “Change the visualization or configure the report” icon.
  3. Click on “Display a table with more metrics” which would trigger a popup
  4. Close the popup window
  5. In my case (PWK_ERR_1.png), i only see one column, everything else disappeared and the “Change the visualization or configure the report” icon did not respond.

Note: The only way to recover was to reload my browser (PWK_EXP_1.png).
Tested on: Firefox 32.0.3 and Safari 8.0 on Mac OSX (Yosemite)
