Another war story: the hardest bug I ever debugged

A peculiar bug in Microsoft Edge caused webcam rotation issues under specific circumstances. The problem only occurred on Windows when clicking an invitation link that opened in a new tab and redirected to a page requesting the internal camera. Despite extensive testing and creating a minimal reproduction, the root cause remained elusive. The bug report filed with Microsoft went unanswered, leaving the mystery unsolved even after Edge's transition to Chromium.
