Please clarify documentation re: Suspense

[qwertie]

This page has a scary sentence:

we recommend to not resort to MobX observables for local component state too quickly, as this can theoretically lock you out of some features of React's Suspense mechanism.

This implies some kind of incompatibility between MobX and Suspense while saying precisely nothing about the nature of the incompatibility or how to avoid it (edit: well, it says to avoid it by using local state which isn't managed by MobX). Please clarify this page to explain

1. What circumstances cause problems
2. What kinds of problem(s) are possible
3. How to avoid problems without rejecting MobX entirely
