Per the PointerEvents spec and Chromium's behavior, untrusted (JS- constructed) MouseEvent coordinates should be floored to integers. PointerEvent overrides this behavior: for non-click types (pointerdown, pointermove, etc.), fractional coordinates are preserved. For click, auxclick, and contextmenu events, coordinates are floored via the MouseEvent base class. Trusted events (created by the user agent) always preserve fractional coordinate values.
