Description

On SDK 12.5.1.GA and iOS 18 / iPadOS 18, if you set the badge value of a Tab, it works only the fist time.

Expected Behavior

The tab must always show the correct badge (for example: tab.badge = '7' --> the badge must show '7', also if it's not the first time i've set it)

Actual behavior

The tab badge is updated only the first time

Reproducible sample

// create a tabGroup and a tab called "myTab"
var window = Ti.UI.createWindow({
    title: 'My Tab'
});
var myTab = Ti.UI.createTab({
    window: window,
    title: 'My Tab',
    icon: 'myicon.png'
});

// add myTab to the tabGroup
tabGroup.addTab(myTab);

// change tab's badge value
myTab.badge = '5';
myTab.badge = '7';  // tab badge remains '5'

// ATTENTION: I've found this workaround: if you modify (for example) the title of the tab, it works (the tab is refreshed?):

myTab.badge = '5';
myTab.badge = '7';  
var tmp = myTab.title;
myTab.title = tmp + ' ';
myTab.title = tmp;  // now the tab is refreshed and the badge shows '7'

Steps to reproduce

Create an app with a Tab Group. In a tab, set the badge value more than one time. See the reproducible sample.

Hi, I've tested

var win1 = Ti.UI.createWindow();

var tab1 = Ti.UI.createTab({
    window: win1,
        icon: '/assets/images/tab1.png'
}),
tabGroup = Ti.UI.createTabGroup({
    tabs: [tab1]
});

tab1.badge = 1;
tab1.badge = 2;
tab1.badge = 3;

tabGroup.open();

and it does show 3 for me. iOS 17 and 18.1 simulator. Android is working fine too
