/**
 * Fake mouse event used internally by `DOMInteractor` to synthesize positioned
 * mouse events. Exported for cross-package reuse within the monorepo, not part
 * of the stable 1.0 consumer API.
 *
 * `pageX`/`pageY` are getter-only accessors on the `MouseEvent` prototype in
 * real browsers (the Angular fixtures run DOM tests in Chromium, ADR-013), so
 * they are shadowed with own properties rather than assigned — plain
 * assignment throws where jsdom happened to tolerate it.
 *
 * @see https://github.com/testing-library/react-testing-library/issues/268
