// FYI: Chrome commits composition if blur() and focus() are called during
// composition. But note that if they are called by compositionupdate
// listener, the behavior is unstable. On Windows, composition is
// canceled. On Linux and macOS, the composition is committed
// internally but the string keeps underlined. If they are called
// by input event listener, committed on any platforms though.
// On the other hand, Edge and Safari keeps composition even with
// calling both blur() and focus().
