/**
 * The element's full text, but only while that text is wider than
 * the box it was given — i.e. only while an ellipsis is being
 * painted. `undefined` the rest of the time.
 *
 * `text-overflow: ellipsis` leaves no trace in the DOM: the glyph is
 * painted by the layout engine and the whole string stays in
 * `textContent`. That is the good news — selection, copy, and every
 * screen reader still get all of it — and the reason this hook has
 * to exist, because nothing in the DOM says "this one is cut off",
 * so a hover affordance cannot be attached declaratively.
 *
 * Measured rather than assumed, since the alternative — always
 * setting a `title` — puts a tooltip on every short status pill in a
 * bay list, which is worse than the problem it solves.
 *
 * The text is returned rather than a boolean so the caller never
 * reads `ref.current` during render.
