Steps to reproduce (updated)

Run updated fiddle

https://zkfiddle.org/sample/kmu10r/6-Custom-Attribute-do-not-resolve-on-template

Current Result

The value="@load(customAtt)" doesn't resolve (returns null)

		<template name="testTemplate2">
			<custom-attributes customAtt="${foo}"/>

			Loading value from custom attribute on parent template:
			<label style="font-weight: bold;"  value="@load(customAtt)"/>

updated: components retrieving a value set on the parent <apply> as an attribute also fail.

The if={bar} doesn't resolve for the 2nd template (resolves in 1st template)

Expected Result

 The value="@load(customAtt)" returns the value stored by <custom-attributes customAtt="${foo}"/>

Debug Information

 related to ZK-5002

Workaround

 Works if the custom attribute is stored on a normal component (not template root).

However, this force the template to have a single component as root.
