Unexpected re-renders, notifyOnChangeProps question

Hi, i have a question about

notifyOnChangeProps

notifyOnChangeProps

. Docs says that the default behavior is

tracked

tracked

, but I see some unexpected re-renders and I'm trying to understand why they are happening.

Please take a look at this example:
https://codesandbox.io/s/quizzical-montalcini-jm2dyf?file=/src/index.js

I expect to see 2 renders: first when

data

data

undefined

undefined

and second when the

data

data

comes from the

queryFn

queryFn

. Somehow i see 3 renders and i can't understand why.
