I'll improve the hook and its nested function in the coming days. Up to now, I just wanted something that works and hopefully passes the CI tests.

Looks good to me.

@teodutu maybe also add a changelog entry to be consistent with the previously templated hook?

Done @RazvanN7.

Since #16097 the regression does not happen any more for me.
