I meant to provide more information before submitting.

1. In the bug list interface, click on filters
2. Under "Saved Filters" - make sure you have more than 1 (I have 3)
3. Click Edit
4. The list of filters appears, on the right side of each filter row is a "X" remove button.
5. Click on the remove button, nothing happens
6. Note: There are no warnings or errors in the console. It acts like there is no code driving the click event.
