Behavior: (1) Click behavior: On mouse down, (x, y) is saved and mouse down sent. When mouse up received within 200ms, mouse up sent to previous mouse down (x, y) position so Chromium interprets as click. (2) Drag behavior: On mouse down (x, y) is saved and mouse down sent. When mouse moves within timeout period of 200ms, webview will continue to wait. Otherwise, mouse move sent to current (x, y) location to let Chromium interpret as drag. (3) These click and drag behaviors make it possible to just send mouse events as they are received and the underlying Chromium implementation will work as expected.
