[TIMOB-6723] Android: TableViewRow fonts change when row is scrolled

If one row in a TableView is set to use a unique font, and the tableview is scrolled back and forth, other rows will pick up the improper font. The following code demonstrates this bug:

Ti.UI.setBackgroundColor('#000');

var win = Ti.UI.createWindow({
  title:'Tableview with Filter',
  backgroundColor:'#fff'
});

var data = [];

for (var c=0;c<=20;c++) {
  data.push({title:"Row "+c});
}

data[3].font = { fontSize: 50, fontWeight: 'bold'};

var tableview = Ti.UI.createTableView({
  data:data,
});

win.add(tableview);
win.open();

Note that only one row has the extra-large font. Launch on Android and scroll the list quickly, repeatedly from top to bottom. As you scroll around, you should see one or more rows with the extra-large font size appear.
