getRealEventTarget() uses Event.path, which is a non-standard API available only in Chromium-based browsers.

It should instead use Event.composedPath() [1], which is a standard API that returns the same result but is supported by all major browsers [2].

Chromium is also deprecating Event.path in favor of Event.composedPath().
