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

lib/lib.dom.d.ts の MediaTrackConstraintsSet から始め、次に advanced と torch を指定して track.applyConstraints を使用しているリンク先の Playground の例を確認します。宣言を報告されているブラウザー機能と比較し、不足しているメンバーを表現すべきかどうかを判断します。完了の条件は、JavaScript に切り替えずに TypeScript の例が受け入れられることです。
