lit-ui-router / SrefActiveClassDirective

Class: SrefActiveClassDirective

Defined in: packages/lit-ui-router/src/sref-active.ts:369

The attribute-part sibling of UiSrefActiveDirective's class handling, with the contract of lit's classMap: bound in class, alone or beside static classes, and toggling only the classes it names.

The first commit writes the whole class list — statics plus whichever of ours apply — as classMap does, which is also what a server rendering render() alone would emit. Every commit after that toggles names on classList, so classes something else added to the element survive.
