很高兴知道头像功能又恢复正常了！

有意思，谢谢！看来我们在处理 highlightjs 捆绑包时未能正确应对这种情况，导致您的网站在使用代码块的任何主题中都会显示控制台错误。以下修复应能使其恢复正常：

Passing th…is directly to \`import()\` will cause it to be resolved on the domain of the current script, which may be on a CDN. Also, the lookup may be blocked with an error like "The base URL is about:blank because import() is called from a CORS-cross-origin script."

这与最近的插件更改完全无关——该逻辑多年来未曾改变。不过，能够修复它总是好的。
