After the update from Symfony 3.1 to 3.2 i cannot close the Symfony debug bar with the [X] button anymore.
The problem occurs in Firefox 50.0.2 on Xubuntu 14.04 64 Bit.
The Firefox console shows a javascript error on click "ReferenceError: event is not defined".
When i use Chromium 53 the close button works as expected, i tested this behavior with an existing and a fresh 3.2 project.
