Ok, so after extensive testings of different settings, here are my suggestions for debugging the problem for people who come after me:

1. Do not rely on testing with only 1 xdebug client! It's trivial to install two editors/IDEs, so get an alternate editor running to make it possible to see whether there is a problem with xdebug, or with the specific client!

2. There can be 3 locations that carry configuration for the xdebug+xdebug client combination! The client(or editor plugin) configuration, the 20-xdebug-conf.ini file (or in php.ini equivalent), and your project-specific configuration. Make sure all 3 locations are in sync in terms of port, path_mapping, etc.
