Typescript/RxJS type inference

Is there any workaround for https://youtrack.jetbrains.com/issue/WEB-29502 and https://youtrack.jetbrains.com/issue/WEB-32336?

Would like to move back to Webstorm from VSCode, but this is a blocker. Being able to infer types as you pipe multiple RxJS operators is a huge productivity boost. Especially when doing something like a switchMap on an observable returned from a service in another file. Webstorm just shows type "any" for everything which is useless.

Any workaround while we wait for this?
