With JavaScript enabled, the saved filter selection box has an inconsistent behavior. [Reset Filter] is the first item listed, meaning that selecting it does not represent a change for that field. Selecting any saved filter results in that choice automatically being submitted, except for [Reset Filter]. To actually reset the filtering, one must click on the Use Filter button.

Just swapping the order of the blank element and the [Reset Filter] entry would serve to make the new selection visible to JavaScript.

However, one may also want to consider the note raised by Issue 0006491.
