Request headers in config are not sent for tiled images

I noticed that when setting an authorization header via the requestHeaders config that the header does not get sent for tiled images.

https://photo-sphere-viewer.js.org/guide/config.html#requestheaders

I am dynamically setting the request header with a token using a function like this:

function changeRequestToken(token: string) {
  viewer.config.requestHeaders = (url) => {
    console.debug(`requesting asset ${url} with token ${token}`);
    return { Authorization: `Bearer ${token}` };
  };
}

If I use the standard equirectangular adapter, the header is sent as expected:

If I switch to the equirectangular tiled adapter, the header gets sent for the low resolution preview image:

But the header fails to be sent for the image tiles:

Let’s got a runtime warning

EquirectangularTilesAdapter fallbacks to file loader because “requestHeaders” where provided. Consider removing “requestHeaders” if you experience performances issues.
