Research direction
Investigate the subtitle download feature in the extension's source code to identify why it continuously calls the API endpoint `https://api.bilibili.com/x/player.so`. Look for a missing stop condition or improper interval. Examine the relevant logic in files related to video subtitle downloading. Review any existing comments or pull requests for clues. Consider adding a debounce mechanism or limiting request frequency.
