Textarea doesn’t break line on ‘enter’ press

I have a project with a lot of libraries, like jQuery, Kendo and AngularJS. After an update with many commits textarea stopped breaking to a new line by [Enter] press. Maybe, somewhere the event has been unbound or a library interrupts. I tried to get listeners for the object by JQuery.data(element), but it got undefined. How can I debug it?

Found a problem. Somewhere in the code:

$(document).keypress(function (e) {
    if (e.which == 13) {
        e.preventDefault();
    }
});

It was used to catch ‘Enter’ press, that led to another page, because menu element was focused on start.
