1, press F 12 to open the webpage source code (some are Fn+F 12), and search for mouseout in the source code.

2. Click on the onmouseout function and find the mouseout in the EventListeners on the right. After expanding, I found that I clicked the Remove button.

3. Click the video play button again at this time, and then leave the webpage interface with the mouse. You can see that it doesn't pause automatically. It should be noted that this setting is only valid this time, and you need to make the same setting the next time you open a webpage, that is, repeat step 1-3.
