< 脚本支持数学公式的ChatGPT Markdown一键复制的反馈
Thanks for your feedback!
This is because the case where mutation.addedNodes[0] is undefined was not handled. I've added an if condition in update 0.4.2 that checks whether mutation.addedNodes[0] exists, this should help.
The code snippet related to this problem is a mutation observer that handles 'headlessui-portal-root', which had worked properly but not elegantly due to this bug.
By the way, I'm seeking for a better way to insert the copy button instead of setting a timeout(which could be invalid in some case but not often), please let me know if you have got a better solution!
确实没有复制按钮，你可以考虑把Upgrade to Plus按钮更换一下
