ContentEditable element -- cursor back to beginning of editable text

I have a contentEditable header. It only allows for one line and doesn't show overflow, so it stays in a specified space on the page, as such:

<h2 id="element" contentEditable="true"></h2>

#element {
    white-space: nowrap;
    overflow: hidden;
}

The user can then edit the text and make it as long as they want. Regardless of how much text the user has entered, I want the cursor to go back to the beginning of the text when they focus out of the header. (This way, if they enter a bunch of text, they will always see the first part of it when they're not editing it).

I've tried the following (home key keycode is 36), but I can't get the cursor to move back to the beginning of the element.

var element = $('#element');

element.on('focusout', function() {
    var evt = $.Event('keydown', {keyCode: 36});
    element.trigger(evt);
});

Any ideas on getting the cursor back to the beginning of the element when I click out of it?

jQuery or vanilla are both fine.

In jQuery. You can clone the current element. Add the clone after the original element and then remove it.

Here is an example:

// target is the editable div and clone is its copy
var target = $(".editableContent");
var clone = target.clone();
target.after(clone).remove();

As @firefoxuser_1 mentioned, the thing to do is to re-set the inner html. However, I found that I had to empty out the inner html, wait a dash, and then re-apply it. Example:

var value = myElement.innerHTML;
myElement.innerHTML = '';
setTimeout(function() {
    myElement.innerHTML = value;
}, 1);

A working (if not particularly good) solution to this is to just reset the html of the element when it is unfocused by using element.innerHTML = element.innerHTML;. Most browsers move the cursor back to the beginning when you do this. However, this is not a good idea if you have a lot of complicated markup in the element, as this causes everything to be repainted.
