1853431 - WebAuthn / U2F Windows security dialog cause media content from every tab and window to drop connection

Status: RESOLVED FIXED

(Core :: DOM: Web Authentication, defect, P2)

Description

[Albert Pal]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/117.0

Steps to reproduce:

• Start a video that's at least 10 minutes long (the faster your Internet connection the longer the video needs to be, ideal candidate is a 24/24h live stream);
• Put that video in picture-in-picture and tweak Firefox browser window and picture-in-picture window sizes so they don't overlap (note: picture-in-picture is not a trigger factor, it just makes visualizing the problem easier);
• Visit https://demo.yubico.com/webauthn-technical/registration or any other WebAuthn or U2F test site you know;
• Trigger a registration or login operation and let Windows security dialog that appears to stay on screen (you don't need a physical key to reproduce).

Actual results:

The Windows security dialog inexplicably cause all media content to stop downloading.eventually cause all media to stop playing.

Expected results:

Windows security dialog triggered by WebAuth /U2F requests should not affect other network connections.
