According to https://github.com/w3c/editing/issues/43 'beforeinput' should only be fired for user actions. Firing it for |execCommand()| might cause some nested events. Or do we want to change the spec? Reproduce Steps [Release 18 (Safari 10.1, WebKit 12603.1.12)]: 1. Go to https://jsbin.com/tevepaw 2. Focus the text 3. Wait for 2 seconds 4. Notice that both 'beforeinput'/'input' will be logged
