// EVENT-TRIGGERING FUNCTIONS
// --------------------------
// This function triggers a very short (1ms long) transition, which will cause
// events to fire for the transition ending.
function triggerShortTransition(node) {
node.style.transition = "1ms color linear" ;
node.style.color = "purple";
// Flush style, so that the above assignment value actually takes effect
// in the computed style, so that a transition will get triggered when it
// changes.
window.getComputedStyle(node).color;
node.style.color = "teal";
}
// This function triggers a very short (1ms long) animation, which will cause
// events to fire for the animation beginning & ending.
function triggerShortAnimation(node) {
node.style.animation = "anim1 1ms linear";
}
// This function triggers a very short (10ms long) animation with many
// iterations, which will cause a start event followed by an iteration event
// on each subsequent tick, to fire.
//
// NOTE: We need the many iterations since if an animation frame coincides
// with the animation starting or ending we dispatch only the start or end
// event and not the iteration event.
function triggerAnimationIteration(node) {
node.style.animation = "anim1 10ms linear 20000";

// GENERAL UTILITY FUNCTIONS
// -------------------------

// (if no parent is specified) as a child of the element with ID 'display'.

// TEST FUNCTIONS
// --------------
// These functions expect to be passed an entry from gEventInfo, and they
// return a Promise which performs the test & resolves when it's complete.
// The function names all begin with "mp", which stands for "make promise".
// So e.g. "mpTestLegacyEventSent" means "make a promise to test that the
// legacy event is sent".
// Tests that the legacy event type is sent, when only a legacy handler is
// registered.

// when listeners of both modern & legacy types are registered. The legacy
