Description Jarred Sumner 2024-06-19 14:36:59 PDT 
The TC39 Regular Expression Pattern Modifiers for ECMAScript proposal has reached stage3 - https://github.com/tc39/proposal-regexp-modifiers

It shipped in V8 in Chrome 125/Edge 125

It adds syntax like the below:

```
/(?i:test)/.test('Test');
```


Currently, this throws an error like:
```
SyntaxError: Invalid regular expression: unrecognized character after (?
```
