// This handler intends to solve a pretty tricky bug with our popup
// transition. The transition is implemented using a large container
// (.content-container) that is moved on the x-axis (from 0 to n*PopupSize)
// inside a wrapper (.container-wrapper) with a hidden overflow. The problem
// is that sometimes the wrapper is scrolled -- even if there are no
// scrollbars. This happen for instance when the newly opened popup has some
// focused field, the browser will automatically scroll the wrapper, resulting
// in moving the whole popup container outside of the popup wrapper. To
// disable this behavior we have to manually reset the scrollLeft position
// whenever it is modified.
'scroll .content-wrapper': function(evt) {
evt.currentTarget.scrollLeft = 0;
}
});
// When a popup content is removed (ie, when the user press the "back" button),
// we need to wait for the container translation to end before removing the
// actual DOM element. For that purpose we use the undocumented `_uihooks` API.
