@deriving({abstract: light}) record labels marked as "never used to read a value"

I'm using:

• ReScript: 9.1.4
• VSCode plugin: 1.4.2

when having this code:

@deriving({abstract: light})
type someType = {field: string}

let f = a => a->field

What happens:

I get a warning on the 2nd line, under "field: string", saying that "someType.field is a record label never used to read a value"

What should happen:

There should be no warning, why? Because I'm actually reading from that field.

Proof: If I change the name of field in the type declaration or use other name after the a-> the code does not compile, which is correct and also probes that that declaration is being used.

Reproduce the warning in the VSCode plugin with the ReScript snippet from the issue, then trace how the plugin reports unused record labels. Done means the warning is absent when field is read through a->field, while changing the label name or accessed field still produces the expected compile failure.
