Describe the bug

also see #8163.

I determined that this was caused by #7948 and has not been fixed in #8110.

I currently use version 2.9.5 to avoid this problem.

I also tried v3.0.0-alpha 7. It has not been fixed at present.

我也遇到了 #8163 这个问题。

我确定这是由 #7948 引入的错误的正则替换导致的，并且并未在 #8110 中得到修复。

我目前使用 2.9.5 版本来避免这个问题。

我也尝试使用了v3.0.0-alpha.7，目前并未得到修复。
