This issue is actually really complicated, because we would have to infer the type of an arbitrary expression to know what properties are available. A workaround would be to extract this to a context entry and access it in a explicitly-typed manner, like this:

1. Make the screenshot above work.
2. Make the originally reported screenshots work.
