Performance discrepancy between Chrome and Edge in extractSectionTracks

Using Microsoft Edge's Performance Tool, we observed up to 3 renderings per cycle. While not ideal, this is acceptable if execution is fast. However, the extractSectionTracks method is notably slow:

Chrome: 60ms

Edge: 330ms

The reason for Edge’s delay is currently unclear. Optimizations should be implemented to improve Edge performance without affecting Chrome. In a second step, the number of follow-up renderings should be reduced to enhance performance and interactivity.
