// or `Enter` to validation the auto-completion. We also need to stop the
// event propagation to prevent EscapeActions side effect, for instance the
// minicard submission (on `Enter`) or going on the next column (on `Tab`).

// with our EscapeActions system, but it's too complicated and hacky to
// monkey-pach textComplete to disable it -- I tried. Instead we listen to
// 'open' and 'hide' events, and create a ghost escapeAction when the dropdown
// is opened (and rely on textComplete to execute the actual action).

// don't want.
