Input listeners are called multiple times on React 19

Polaris

Hi,

On React 19, the onChange event for the checkbox (and probably switch and maybe all the other fields) are called twice.

Reproduction:

<s-checkbox label="Test" onChange={() => console.log('CALLED')}></s-checkbox>

On React 19, clicking the checkbox will output “CALLED” twice.

On React 18, only once as expected.

Thanks!

I was able to replicate this. Looking into it

Hi @bakura10

There was an update released related to this - this should be fixed on your side now.

I’m still seeing this. It looks like the React shim for Polaris should not be adding an event for onChange in React 19. I created a new thread: onChange on Polaris web components still fires twice on React 19.
