sap.ui.unified.CalendarAppointment customData is not written to DOM

[daletman]

What is the issue and how can we reproduce it?

Using the following code for a SinglePlanningCalendar:

<appointments>
	<unified:CalendarAppointment
		title="{Name}
		startDate="{
			path: 'Start',
			type: 'DateTimeOffset',
			constraints: {
				precision: 7,
				v4: true
			}
		}"
		endDate="{
			path: 'End',
			type: 'DateTimeOffset',
			constraints: {
				precision: 7,
				v4: true
			}
		}"
	>
		<unified:customData>
			<c:CustomData
				key="asd"
				value="qwe"
				writeToDom="true"
			/>
		</unified:customData>
	</unified:CalendarAppointment>
</appointments>

Error:

The DOM does not contain any data-asd="qwe".

Expected behavior:

Every div for a appointment should contain data-asd="qwe".
It's a valid aggregation: https://ui5.sap.com/1.134.0/#/api/sap.ui.unified.DateTypeRange%23aggregations

Which OpenUI5 version is your project targeting?

1.134

Is the issue device- or browser-specific?
