Removed by microsoft/TypeScript-DOM-lib-generator#715. The removal was intentional, but I'll revisit the decision. @saschanaz do you have an opinion on this?

Never mind, I mis-remembered the change. Blob and URL are available globally, and can be referenced on window. However, in 3.6, window: Window & typeof globalThis. You'll need to update your declaration of win for 3.6 to match it.
