<refactor>: Prepare for TypeScript v3.2.2 (#14847)
<refactor>: Prepare for TypeScript v3.2.2 (#14847)

We're upgrading TypeScript to v3.2.2 in google3. This PR suppresses the
compilation errors without actually upgrading the version of TypeScript.

According to the comments, the top and bottom properties in
ExtendedScrollToOptions are mutually exclusive. However when rewriting
the bottom offset as a top offset both properties are defined. With the
improved type inference in TypeScript 3.2 this is now a compilation
error.
