/**
* The design spec calls for the an outline to wrap the entire element when the template's anchor/button has :focus-visible.
* Usually, we would use :focus-within for this. However, that matches when a child element has :focus instead of :focus-visible.
*
* Currently, the browser does not have a pseudo selector that combines these two, e.g. :focus-visible-within (WICG/focus-visible#151)
* To make our own :focus-visible-within functionality, we use event delegation on the host and manually check if the focus target (denoted with the .fvw class) matches :focus-visible. We then map that state to some styles, so the entire component can have an outline.
