[Question] Using `callback` and `preservedCallback` inside `useRefEffect`

[jin-Pro]

slash/packages/react/react/src/hooks/useRefEffect.ts

Line 15 in 570759f

const preservedCallback = usePreservedCallback(callback);

As you can see from the above code, you created a 'preservedCallback' using 'usePreservedCallback' to keep a reference to the 'callback'.

[preservedCallback, ...deps]

When wrapping 'useCallback' to maintain a reference to 'effect', the return value of 'useRefEffect'. you use 'preservedCallback' created in 15L as a dependency.

slash/packages/react/react/src/hooks/useRefEffect.ts

Line 24 in 570759f

const cleanup = callback(element);

But, the function used inside 'effect', which is the return value, uses 'callback', not 'preservedCallback'.

Is this intended behavior?

[ 1 ]

If you don't want to affect the 'effect' reference change due to the reference change of 'callback', use 'preservedCallback' in deps, but the actual operation is to use callback.

I'm wondering if I need to use 'preservedCallback' when using 'eslint-disable'.

To avoid confusion in code

slash/packages/react/react/src/hooks/useRefEffect.ts

Line 24 in 570759f

const cleanup = callback(element);

I'm thinking that maybe I should use 'preservedCallback' instead of 'callback' in the above code.
