Putting a regular expression on a new line in JavaScript or TypeScript breaks the highlighter.
Steps to Reproduce:

1. paste this:

1
	/ f(/u/g)
function f(_: RegExp) {
	return 1;
}

2. make sure the language mode is set to TypeScript
   Expected:
   Same highlighting as this:
   

Actual:

Theme: @id:vscode.theme-defaults: Dark +

在 VS Code 中使用 TypeScript 语言模式，通过提供的 TypeScript 代码片段重现该问题，然后检查仓库中的 TypeScript TextMate 语法文件。将高亮显示与预期示例进行比较，并验证将正则表达式放在新行上不再会破坏后续代码的高亮显示。
