Fixes Udemy bug: if UI shows 2x speed, ensure video plays at 2x after lecture change.
Fixes a common Udemy bug where the video playback speed resets after changing lectures, even though the UI still shows your chosen speed (e.g. 2x). This script keeps the video playback speed in sync with the UI display.
On Udemy, you might see "2x" speed in the corner, but the video is actually playing at normal speed after changing lectures. This script ensures your playback speed is always what the UI says it is.
