The parameter value is empty.

### To Reproduce
<!--
Your best chance of getting this bug looked at quickly is to provide an example.
-->
preload.js

> const {contextBridge} = require("electron");
> contextBridge.exposeInMainWorld("WebVC", {
>   writeBlobToFile: (blob) => {
>     console.log(blob);
>   }
> });

renderer.js

> window.WebVC.writeBlobToFile(new Blob(["Hello World"]));
