title: ExtJs rownumberer issue
body: <p>I am using <strong>ExtJs Gird</strong> for displaying data from my DB. I am using <code>{ text: 'No.', xtype: 'rownumberer' }</code> to number the rows. Everything is fine except that the <strong>rownumberer</strong> is not working as expected in <strong>google chrome</strong>. If I have 140 records, the <strong>rownumberer</strong> is working fine till the <strong>99th record</strong> and after that for all the rows it displays some dots like (<strong>...</strong>). Anybody know why this is happening?</p>
