Updating to 4.9.2 has broken my webpack build with typescript error:

ERROR in node_modules/mobx/lib/types/observablemap.d.ts(42,5):
TS2416: Property '[Symbol.toStringTag]' in type 'ObservableMap<K, V>' is not assignable to the same property in base type 'Map<K, V>'.
  Type 'string' is not assignable to type '"Map"'.

Reverting to 4.9.1 fixes this.
