Ability to set referrer policy on Map's transformRequest function

I am trying to implement url restrictions on a project using Mapbox. Our global referrer policy is set to "same-origin". In the transformRequest function, I'd like to be able to return a referrer policy for the fetch request. Right now if I add it to the request parameters it will not be included.

This is the Mapbox fetch request. I've tried setting it on the headers but that doesn't work. If I spread the requestParameters in, it does work (eg {...requestParameters} before method)

function makeFetchRequest(requestParameters                   , callback                       )             {
    var controller = new window$1.AbortController();
    var request = new window$1.Request(requestParameters.url, {
        method: requestParameters.method || 'GET',
        body: requestParameters.body,
        credentials: requestParameters.credentials,
        headers: requestParameters.headers,
        referrer: getReferrer(),
        signal: controller.signal
    });

Can Mapbox add this as a supported parameter?

Start at the makeFetchRequest entry point shown in the issue and trace how transformRequest request parameters become the Fetch Request options. Support a referrer policy parameter alongside the existing options, then verify that it is included in the constructed request and covered by the relevant request tests.
