// Until recently, Chrome on most platforms relied solely on a heuristic in
// ui::KeyEvent construction to determine if they are repeat key events. Chrome
// recently shifted to reading key repeat information from the native OS key
// event on all platforms (see https://crbug.com/40940886), which theoretically
// makes this heuristic redundant.
//
// This feature flag is used to gradually turn off this heuristic and also
// serves as an emergency killswitch in case turning it off causes major
// issues. See tracking bug https://crbug.com/411681432 for more info.
