React version: 0.0.0-241c4467e (current `next`) and 16.12.0
Devtools: 4.4.0 (1/3/2020). [...] Created from revision f749045a5 on 1/3/2020.

## Steps To Reproduce

1. Visit https://codesandbox.io/s/usedebugvalue-complex-types-3x877
2. Inspect `App` Component
3. `NoHooksAtAll` displays no hooks at all
4. `IgnoredComplexValue` displayes the custom hook but without a value
5. `NoHooksAtAll` displays the custom hook with its value


Link to code example:


## The current behavior
Complex values (and custom hooks) are sometimes not displayed

## The expected behavior

Implementation of components and hooks should not affect if these are displayed.
