 As a public university website mandated to achieve WCAG 2.0 accessibility
 standards, we've found that the Categories widget presents navigation
 issues when displaying categories in a dropdown selector.

 The WCAG issue at hand is SC 3.2.1 On Focus, specifically that forms
 should not be submitted automatically when a component receives focus.
 This is what happens when using the Categories widget's dropdown selector.

 For mouse users, the dropdown is a fairly intuitive process that involves
 simply clicking to expand the dropdown and then clicking to select a
 cateogory to explore. Clicking the category immediately opens a page
 populated by posts with that category.

 For keyboard users, however, the dropdown is essentially unusable because
 it assumes that the user has selected the first category they pause on and
 immediately opens a page based on that. There's no way to scroll down the
 menu and see what the options are before making a selection.

 WCAG standards require a "Submit" button or similar action to initiate
 that navigation to a new page, not simply resting the focus on a category.
