RegExp named capture groups don't get transpiled

TypeScript Version:
3.7.2 (3.7.4 and nightly (3.8.0) as well)

Search Terms:
Named capture groups
Named capturing groups
Regex
ES2018.RegExp

Expected behavior:
The named capture group in the regex gets transpiled to the correct target (es5 in our case). Something like what @babel/plugin-transform-named-capturing-groups-regex does?

Actual behavior:
The named capture group ends up in the compiled code while only Chrome currently supports this.

Code

const regex = /^(?<name>[A-Za-z]+)/;
const match = regex.exec('MatchThis-NotThis');
console.log(match);

Additional information
I'm not 100% sure if this is something that TypeScript actually should be doing so if that's not the case I'd like to get some details on how to properly transpile this.

Comienza con el tratamiento de los literales de expresiones regulares por parte del compilador de TypeScript y reproduce el problema en el Playground enlazado, con ES5 como objetivo. Compara el comportamiento solicitado con la transformación de Babel enlazada y con el issue relacionado #31241; se considera completado cuando los grupos de captura con nombre se gestionen correctamente para el objetivo, o cuando el issue documente claramente por qué TypeScript no los transformará.
