Gatsby : Cannot execute componentWillReceiveProps when running 'gatsby develop`

Question

Can anyone explain why when running gatsby develop the Child component’s lifecycle method componentWillReceiveProps is ignored and it is re-mounted with every new change - whereas when building the static version of the app, the Child's componentWillReceiveProps lifecycle method is executed correctly.

See attached ‘dev’ and build gifs, or checkout the source.

Answer 1

This issue was resolved by removing gatsby-plugin-preact>

Answer 2

Thanks to @Nenu, I discovered that the issue is elsewhere. Using the example code in a fresh gatsby project worked as expected.
