[0.8] Binding the value of an input box with {{value::input}} loses caret index

[Sleeckx]

When binding a value to an input box using the custom notify event syntax, you lose the caret index when adding a character. The selectionStart always jumps to the end.

<input value="{{value::input}}" />

When digging in the _effects.html_, the value of the input is set, even though it has the same value already.

_applyEffectValue: function(value, info) {
    var node = this._nodes[info.index];
    // TODO(sorvell): ideally, the info object is normalized for easy
    // lookup here.
    var property = info.property || info.name || 'textContent';
    // special processing for 'class' and 'className'; 'class' handled
    // when attr is serialized.
    if (info.kind == 'attribute') {
        this.serializeValueToAttribute(value, property, node);
    } else {
        // TODO(sorvell): consider pre-processing this step so we don't need
        // this lookup.
        if (property === 'className') {
          value = this._scopeElementClass(node, value);
        }
        return node[property] = value;
    }
}

At the end of this method return node[property] = value; causes the input's value to be overwritten with the same value which moves the caret to the end.

Can we maybe change it to the following?

if(node[property] !== value)
    node[property] = value;

return value;
