Summary	0002403: Reinit debugger for requests in FrankenPHP worker mode
Description	The current implementation is not ideal to debug worker mode. You need to: add your breakpoint before starting the worker call xdebug_connect_to_client (and that's included in symfony runtime) but it bypasses the xdebug.start_with_request=trigger configuration It's possible to offer a better support of worker mode by hooking with frankenphp and enable / disable profiling when needed.
Tags	No tags attached.

Operating System
PHP Version	8.5.0-8.5.4

Xdebug will try to connect to an IDE when a request starts, or when you call xdebug_connect_to_client, or when it sees a request triggered through its control sockets (https://xdebug.org/docs/step_debug#control_socket).
