1826841 - Update panel-list and panel-item to match the menu spec, use design tokens

Status: NEW

We have a spec for menus [1] that seems like it was mostly intended for chrome but it would likely make sense to update panel-menu to follow that spec for in-content as well.

We should be able to update the styles to use design tokens while we do this.

Heads-up that bug 1998985 will make us use panel-list for the address bar's and search bar's search engine button dropdown menus, so panel-list would appear in a fairly prominent place in primary UI where more folks might notice that panel-list looks and feels not quite like our other more native menus. I imagine that might elevate this bug's priority, although from what I can see this bug is already well on your radar. :)
