Message:

Widgets: Add Customizer preview support to the Category widget when navigating to a category via dropdown.

Switch to using a form that is submitted as opposed to making a direct JavaScript call to change the window.location. This ensures the Customizer is able to inject the customized state into the request.

Fixes #41671.
