Investigate why select._wrapperState.initialValue is necessary

[nhunzaker]

Uncovered during @raunofreiberg's select work (#13389).

select._wrapperState.initialValue is only ever assigned, never referenced. Can it be removed?

Example:
https://github.com/facebook/react/blob/master/packages/react-dom/src/client/ReactDOMFiberSelect.js#L191

It would be great if someone could investigate this, and figure out if it can be removed.

Nominating @raunofreiberg for this, but I don't want to create work for them :)

I want to say that this is an artifact of older defaultValue handling for selects?

[nhunzaker]

Removing it completely appears to have no effect on the test suite.

@nhunzaker Can I take this one? This is my first time contributing to React

Purely from reading the code, it seems like your assessment of initialValue not being used seems correct. Happy to investigate further

[nhunzaker]

Go for it!
