【问题描述】：
我已将我们的应用程序更新到 Angular v12。 在 Chrome 中，我收到此错误（成功编译后）：
未捕获的 SyntaxError：无效的正则表达式： /^\d{4}-\d{2}-\d{2}(?:T\d{2}:\d{2}:\d{2}(?:.\d+)?(? :Z|(?:(?:+|-)\d{2}:\d{2}))?)?$/: 正则表达式太大
这个正则表达式可以在 node_modules/@angular/material/bundles/material-core.umd.js 第 854 行找到：
var ISO_8601_REGEX = /^\d{4}-\d{2}-\d{2}(?:T\d{2}:\d{2}:\d{2}(?:\.\d+)?(?:Z|(?:(?:\+|-)\d{2}:\d{2}))?)?$/;
在 Angular 11 中，我们没有收到这个错误，所以我想知道为什么它现在会出现，以及如何解决这个问题。我已经尝试将 @angular/material 降级到 v11，但它会引发完全相同的错误。
