/**
 * Fills in where a component is defined when the page could only say how it
 * was registered. The page names a class's `customElements.define` call by a
 * number (`defineId`) on tree nodes and timeline events, and by its stack
 * (`defineFrames`) on details. The host's resolver (the extension maps them
 * through the page's sourcemaps) turns frames into a `source`, which is set
 * on whatever carried the number or the stack before it goes on.
 *
 * A number is asked about once: the first unknown ids of a page go to it in
 * one `define-frames` command, its answer is consumed here, and the result
 * is kept per page and id, so later events and nodes are filled on the spot.
 *
 * Order is kept. Events that must wait hold the ones behind them, and
 * inspector messages do the same among themselves, so a later `gone` or
 * fresher details cannot be overtaken by an older answer. With nothing held,
 * a message passes straight through. A resolver that fails, or an answer
 * that takes longer than {@link RESOLVE_TIMEOUT_MS}, leaves things as they
 * came, and the miss is remembered rather than retried.
