Cypress & Chrome Test Third Party Cookie Phase Out

[iepoch]

Current behavior

As an SDET I am trying to test the new Chrome Test Third Party Cookie Phaseout flag. Currently Cypress will show the browser is set to "enabled" for the third-party-cookie-phaseout although the actual flag shows as disabled.

Desired behavior

We should have a flag to set in Cypress to allow the third party phase out to be enabled and that the actually setting shows enabled. IE

Test code to reproduce

 on('before:browser:launch', (browser={}, launchOptions) => {
    if (browser.family === 'chromium') {
      launchOptions.args.push('--test-third-party-cookie-phaseout');
      return launchOptions;
    }
  }
);

Would like to know if Cypress runs this setting but because Cypress needs to Frame Chrome can not provide the setting update because of the frame or if it's Google Issue that it's not toggle it based on Cypress Framing?
