New Portal Designer (In Preview) not adhering to the the null check expression

### Severity

P4 - Low (Cosmetic/minor inconvenience)

### Describe the Bug with repro steps

The workflow expression should not cause an exception when using a null check with "?" when the property does not exist e.g. defaultValues does not exist here:
`{
"type": "Compose",
"inputs": "@addProperty(variables('RequestMessage'), 'defaultValues', parameters('globalOptions')?['specific']?[workflow().name]?['defaultValues'])"
}`

Exception raised when running my workflow with a payload in the preview designer:
> InvalidTemplate
> Unable to process template language expressions in action 'TransformRequest-_Add_Default_Values' inputs at line '0' and column '0': 'The workflow parameter 'globalOptions' is not found.'.

The same run with payload completes successfully in the old designer.

### What type of Logic App Is this happening in?

Start by reproducing the expression in the New Portal Designer preview with the workflow JSON provided, then compare its handling with the old designer. Trace the preview designer's expression-evaluation entry point and verify that the null-safe lookup does not raise the missing-parameter exception. Done means the workflow completes successfully with the expression shown and existing behavior remains intact.
