Should we just merge the two selectors to

.dropdown-item:not([disabled])

I don't think we have any dropdown-item instances that are not children of
paper-dropdown-menu-light, or cr-shared-menu (same question for lines 58-59).

if that's specific enough, sgtm

alsoooo, :-webkit-any() is a thing

:-webkit-any(iron-dropdown, paper-dropdown-menu-light)
.dropdown-item:not([disabled])

+      paper-dropdown-menu-light .dropdown-item:not([disabled]),
       cr-shared-menu .dropdown-item:not([disabled]),
       iron-dropdown .dropdown-content paper-item {
         @apply(--settings-actionable);
