/**
 * A click in the panel says which campaign it means.
 *
 * Two changes that were each correct alone produced this between them. The
 * panel became clickable, every step and row carrying a sentence about "this
 * campaign". Separately the panel became a view: a tab click changes what is
 * on screen without moving what the chat is working on, which is the whole
 * point of the note that says so.
 *
 * Together, "this campaign" is written while looking at one campaign and read
 * by an agent holding another. The step click also submitted on its own, so
 * one click on the wrong tab silently edited the other campaign.
 *
 * Both halves are asserted here: the sentence names its campaign, and it is
 * the one being looked at rather than the one in focus.
