Release Notes Persisted

Fixed an issue which caused print settings to not work properly when printing silently.

I tested the fix in v16.0.0-beta.6. It looks like the header is not being respected, but the rest of the settings are.
It always print the header with the window's title.

Is there any way to workaround this?

Test code:

(async () => {
  const {app, BrowserWindow} = require("electron");

  await app.whenReady()

  const window = new BrowserWindow();
  await window.loadURL("https://www.electronjs.org/");
  window.webContents.print(
    {
      header: "I am header",
      footer: "I am footer",
      deviceName: "Microsoft Print to PDF",
      landscape: true,
      silent: true,
    });
})();

Looks like setting the document.title using the js before printing would be the workaround.
await window.webContents.executeJavaScript("document.title = 'I am header'");
