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

从 lib/lib.dom.d.ts 中的 MediaTrackConstraintsSet 开始，然后查看使用 advanced 和 torch 调用 track.applyConstraints 的关联 Playground 示例。将该声明与报告的浏览器功能进行比较，并确定是否应表示缺失的成员；完成的标准是 TypeScript 示例在不切换到 JavaScript 的情况下被接受。
