Describe the Bug

Whenever you have millennium installed and try to go to a cloudflare protected website, or any type of captcha (even paypal captcha when adding funds to steam wallet) it always says that you are a robot or has a continuous loop to say that you are not a robot. Easiest to try in shift tab menu browser.

Steps To Reproduce

Prerequisites

• Steam Client installed
• Millennium installed and active
• Any website protected by Cloudflare or other CAPTCHA service

Reproduction Steps

1. Launch Steam with Millennium enabled.
2. Open the Steam Overlay browser (Shift+Tab) or any Steam embedded browser view.
3. Navigate to a Cloudflare-protected website (e.g. csstats.gg).
4. Complete the "Verify you are human" challenge.
5. After successful verification, refresh the page or navigate to another Cloudflare-protected website.

Expected Result

• The verification challenge should complete successfully.
• The user should be able to access the website normally.
• Verification state should persist across requests as intended.

Actual Result

• The challenge enters a continuous verification loop.
• Cloudflare repeatedly asks the user to verify they are human.
• Access to the website is never granted despite successful completion of the challenge.
• Similar behavior occurs with other CAPTCHA-protected services, including PayPal CAPTCHA prompts when adding funds to a Steam Wallet.

Additional Information

• Removing Millennium resolves the issue.
• Deleting Steam's cookie database (%LOCALAPPDATA%\Steam\htmlcache\Default\Network\Cookies) temporarily resolves the issue until a new Cloudflare verification cookie is created.
• Issue reproduces consistently across multiple Cloudflare-protected websites.
