AI QA agent passed blank canvas: hidden tab throttling to blame
An AI QA agent using Claude and Chrome MCP falsely reported all features working on a canvas tool that was actually blank. The root cause was browser throttling of requestAnimationFrame in hidden tabs, which stopped rendering entirely. The author provides fixes including using visible tabs and requiring behavior checks beyond code-path health.

The piece is a practical debugging case study, but its real value is highlighting a systemic blind spot in AI-driven testing: agents can't see what browsers hide.
