[Discussion] Mobx Devtools vs React Devtools inconsistent highlighted updates

Hi,

I'm getting inconsistent results when using the highlight updates feature of Mobx React Devtools and React Devtools.

Using Mobx-React-Devtools the Mobx components are only highlighted twice (when they render the first time and after being updated when I click the update button:

But when I use React Devtools the Mobx components are always being highlighted suggesting that they are always being rendered:

Is this expected?

Here is a link to the sample project on CodeSandBox in case you want to try it out.

I've also noticed that on both Mobx components there's an update method being called every single time:

I'm mentioning it since I don't see something similar for the sample React PureComponent that I'm using without Mobx.

Start with the linked CodeSandbox sample and reproduce the inconsistent highlight updates in Mobx-React-Devtools and React Devtools. Compare the highlighted renders and the reported update calls, then determine whether the behavior is expected or indicates a bug; the issue does not name a source file or test to update.
