Bulk bouncing fails ?

[MikeGriffinReborn]

If I do this on a context menu click it works perfectly ...

function indicateOnline(e) {
	let marker = e.relatedTarget.repeater.marker;
	marker.toggleBouncing();
}

Where as this fails ??

function refreshOnlineRepeaters() {
	let arrayLength = g_MasterRepeaters.repeaters.length;

	for (let i = 0; i < arrayLength; i++) {
		let repeater = g_FilteredRepeaters.repeaters[i];

		if (i % 20 === 0) {
			repeater.marker.toggleBouncing();
		}
	}
}

The error is ...
