Cannot hover or select grid row after store.sync() call
<p>After calling <code>store.add(newRecord);</code> a new row is added to the grid and I can select/hover/deselect it, but after calling <code>store.sync()</code> to save that row to DB, it cannot be selected/hovered/deselected anymore.</p>

<p>These actions only work after reloading the page (F5) or calling <code>store.reload()</code></p>

<p>How I can fix it? I don't want to use reload.</p>
