有些时候使用navigator.clipboard.write会出现DOMException: Write permission denied.错误导致无法写入剪贴板。
建议：对它加上catch，失败的话使用再进行第二种方式document.execCommand("copy")

Actually, no evidence suggests that document.execCommand("copy") could do a better job than navigator.clipboard.write.
If this error is not reproducible in a definite way, then I think the best solution for the UserScipt is to catch the error and call GM_setClipboard again.

It would be great if you can find a way to reproduce it, so that we know what goes wrong.
