Steps to Reproduce

https://zkfiddle.org/sample/2vqp1q4/6-Binding-firing-not-trigger-due-to-shadow-element-operators

Run fiddle

Click "update InBean2"

Current Result

The 2nd result doesn't update

The 4th result (same binding) updates

Expected Result

The 2nd result should trigger

Debug Information

Happens only when a number of factors are met:

• Inside a shadow element, First child of shadow element has a binding (any kind, any target)
• failing binding target a property of a bean (ex: @load(bean.property))
• another binding use the bean with an operator below the failing binding (ex: @load(empty bean))
• the bean is part of a form proxy object

Workaround

multiple based on which is the easier to implement:

• Add a div (or other component) without bindings as child of the shadow element
• Add a custom-attribute binding the bean to the component holding the failing binding (ex: foo="@load(bean)")
