MediaTrackConstraintsSet misses torch

I'd like to use the torch constraint but typescript complains as its missing in the defined set.

I understand the advanced field is controversial and might even be removed, but yet I think it is a bad idea if typescript disallows using the features when they are implemented...

TypeScript Version: 3.8.3
also master: https://github.com/microsoft/TypeScript/blob/master/lib/lib.dom.d.ts#L770

Code

track.applyConstraints({ advanced: [{ torch: this.torch }]});

Expected behavior:
not to be restricted in functionality when using typescript

Actual behavior:
I can't use this feature.. I have to switch to JS

Playground Link: Playground Link

Inizia in lib/lib.dom.d.ts, in corrispondenza di MediaTrackConstraintsSet, quindi esamina l'esempio Playground collegato che usa track.applyConstraints con advanced e torch. Confronta la dichiarazione con la funzionalità del browser segnalata e determina se il membro mancante debba essere rappresentato; il lavoro è completato quando l'esempio TypeScript viene accettato senza passare a JavaScript.
