Experience Manager: natural group ordering only works in Firefox

There's this piece of Ext code in file community/channel-manager/frontend/src/main/resources/org/onehippo/cms7/channelmanager/channels/ChannelIconPanel.js:

// create non associative array
dataObject = [];

Ext.iterate(groups, function(groupId, group) {
 group.channels.sort(function(channel1, channel2) {
 return channel1.name > channel2.name;
 });
 dataObject.push(group);
}, this);

dataObject.sort(function(group1, group2) {
 return group1.name > group2.name;
});

The sorting logic works on Firefox 85.
It does not work on Chrome 88, Edge 88.

(apparently sorting arrays is known to be different across browsers).

Reproduction

Visit https://cms.demo.onehippo.com with Chrome and with Firefox, open the Experience Manager's, icon panel, see the differences.

Suggested solution 
In a client case with an extra customization, the sorting is actually not wanted, so the request is to just remove the sorting code, resulting in the same behavior across browsers.

As extra, we can make the sorting work for all browsers but then optional.
