Race condition causing assets to load from wrong location in Electron when launched with Playwright

Question

I have an electron app I am trying to add playwright tests to, and when I launch it using the playwright _electron.launch(), I have some SVG files that are used in my CSS trying to load from the node_modules/electron/dist/resources/electron.asar file, instead of from the Webpack /build directory. Launching it manually from the command line works fine, without rebuilding or anything.

Any ideas what could cause this?

When I inspect the icon-load element in devtools element tab, the URL shows up like so:

.icon-load {
    background: url(file:///F:/Programming/REDACTED/node_modules/electron/dist/resources/electron.asar/renderer/287f560038de84fa9ced.svg);
}

So far I have tried verifying body.baseURI as well as a few different options on _electron.launch().

Devtools console session:

window.$("body").baseURI
"file:///F:/Programming/REDACTED/build/"

launch-electron.js:

// Launch Electron app.
const electronApp = await electron.launch({
  args: ["."],
  //cwd: "F:\\Programming\\REDACTED", // no change
  //bypassCSP: true, // no change
});

Update 2: Refreshing the page causes the SVG files to load from the correct location!! We appear to have a race condition with some kind of context switching in the electron launch. I'll add a snippet of my Webpack config again:

module.exports = {
  context: __dirname + "/renderer",
  entry: "./App.js",
  output: {
    path: __dirname + "/build",
    filename: "bundle.[fullhash].js",
  },
  stats: {
    errorDetails: true,
    children: true,
  },
  module: {
    rules: [
      {
        test: /App\.js$/i,
        loader: "expose-loader",
        options: {
          exposes: {
            globalName: "FF",
          },
        },
      },
      {
        test: /\.css$/i,
        use: ["style-loader", "css-loader"], // disabling URL loading in CSS loader makes app load but without CSS images
      },
      {
        test: /\.(jpg|png|ico|svg)$/i,
        type: "asset/resource",
      },
    ],
  },
};
