@ScopeParam with scopes = Scope.AUTO would look up an attribute in Execution scope

Steps to Reproduce

1. run the attached zul
2. check <label value="@load(vm.value)"/>

Current Result

renders nothing.

Expected Result

should render through @ScopeParam: value in execution, be consistent with EL resolving result.

Debug Information

• the EL expression ${exec} can resolve the attribute exec in execution scope.
• vm.value is from @ScopeParam(scopes = Scope.AUTO, value = "exec")

Alternative

use @ExecutionParam
