Hi, I'd like to work on this issue

Based on the discussion in microsoft/TypeScript-DOM-lib-generator#1300, I think there is no need to fix this issue from within TypeScript's codebase.

The main reason for this issue is because preservesPitch is only available in the standard form in Chrome, and is prefixed in other browsers. Once the other browsers implemented it, the lib.dom.d.ts generator will be able to generate the type correctly.

Here are the relevant issues to track in Safari and Firefox:

Hi, thanks for the info, didn't know that it only works with a prefix on Firefox and Safari.
