React-toolbox: Checkbox onChange returns proxy, not value

[DarkoKukovec]

According to the documentation, the onChange function should get the value, but it gets a Proxy object instead.

Tested on 1.3.0, also happening in the playground (since the proxy object is truthy, the checkbox will always be checked)

I rolled back to 1.2.5 and everything works as expected.

I am having a same issue. Seems like onChange is getting fired twice, and returns the proxy on the second run.
