/**
 * Minimal additive bridge so the editor surface (chrome side) can drive the
 * renderer's ProseMirror commands without the renderer importing chrome or the
 * surface importing renderer internals. The renderer registers a runner while
 * an element is being edited; the property bar calls it. PR1-shaped: the
 * playback/uncontrolled path never registers (editable=false), so behavior
 * there is unchanged.
